Fluid Mechanics – Introduction

01-Fluid Mechanics example - Static and Turbulent Flow - Analysis -Dynamic  analysis - CFD

Fluid Mechanics is that section of applied mechanics, concerned with the statics and dynamics of liquids and gases.

A knowledge of fluid mechanics is essential for the Mechanical engineer, because the majority of Mechanical processing operations are conducted either partially or totally in the fluid phase.

The handling of liquids is much simpler, much cheaper, and much less troublesome than handling solids.

Even in many operations a solid is handled in a finely divided state so that it stays in suspension in a fluid.

Fluid Statics: Which treats fluids in the equilibrium state of no shear stress

Fluids and their Properties

Fluids

In everyday life, we recognize three states of matter:

  • solid,
  • liquid and
  • gas.

Although different in many respects, liquids and gases have a common characteristic in which they differ from solids: they are fluids, lacking the ability of solids to offer a permanent resistance to a deforming force.

fluid is a substance which deforms continuously under the action of shearing forces, however small they may be.Conversely, it follows that:
If a fluid is at rest, there can be no shearing forces acting and, therefore, all forces in the fluid must be perpendicular to the planes upon which they act.

Shear stress in a moving fluid

Although there can be no shear stress in a fluid at rest, shear stresses are developed when the fluid is in motion, if the particles of the fluid move relative to each other so that they have different velocities, causing the original shape of the fluid to become distorted. If, on the other hand, the velocity of the fluid is same at every point, no shear stresses will be produced, since the fluid particles are at rest relative to each other.

Mechatronics / Introduction

September 16, 2011

Mechatronics is a word originated in Japan in 1980s to denote the combination of technologies which go together to produce industrial robots.

A formal definition of Mechatronics is “the synergistic integration of Mechanics and Mechanical Engineering, Electronics, Computer technology, and IT to produce or enhance products and systems.’’

The various fields that make up Mechatronics is shown in Fig

01-what is Mechatronics-Introduction-Mechanical and Eletronics

Examples of such systems are

  • Computers,
  • Disk drives,
  • Photocopiers,
  • Fax machines,
  • VCR,
  • Washing machines,
  • CNC machine tools,
  • Robots, etc.

Today’s modern cars are also mechatronics product with the usage of electronic engine management system, collision detection, global positioning system, and others.

01-mechatronics-design-combination of mechanical and electronics

The concept of mechatronics is very important today to meet the customers’ ever increasing demands and still remain competitive in the global market. Very often a mechanical engineer without the mechatronics background is considered equivalent to a mechanical engineer without the engineering drawing knowledge.

Mechatronics requires thinking products and processes so transverse. Mechatronics is “burst the walls, with a steering matrix. The pilot at the highest level of the enterprise is essential in this context, to afford in front needs to be implemented.

The design should no longer be sequentially: the mechatronics approach requires thinking about the product as a whole (all skill areas at a time) and not by separating the mechanical part, then electronics, then the sensor – actuators and computers at risk to achieve additional cost prohibitive.

01-robot-arm-future-mechatronics

The project manager must master the various areas and not be an expert in one of mechatronics technology: It was necessary to avoid watching the draft with an eye mechanics or electronics. The pilot is here, as elsewhere, the role of a conductor, not a virtuoso.

The phases of integration are sensitive, such that an electronic assembly in a machine shop (or vice versa). There are telescoping and areas of project management and competence, which involves work that is done jointly, to ultimately obtain not a purely mechanical or purely electronic, but a set that combines the advantages of 2, which can not be separated.

Mechanical Engineering-What is It? / What Mechanical Engineers do?

September 16, 2011

Mechanical engineers design and develop everything you think of as a machine – from supersonic fighter jets to bicycles to toasters. And they influence the design of other products as well – shoes, light bulbs and even doors. Many mechanical engineers specialize in areas such as manufacturing, robotics, automotive/transportation and air conditioning. Others cross over into other disciplines, working on everything from artificial organs to the expanding field of nanotechnology. And some use their mechanical engineering degree as preparation for the practice of medicine and law. The mechanical engineer may design a component, a machine, a system or a process. Mechanical engineers will analyze their design using the principles of motion, energy, and force to insure the product functions safely, efficiently, reliably, and can be manufactured at a competitive cost.

Mechanical engineers  work in the automotive, aerospace, chemical, computer, communication, paper, and power generation  industries. Mechanical engineers will be found in virtually any manufacturing industry. Increasingly, mechanical engineers are needed in the environmental and bio-medical fields. Indeed virtually every product or service in modern life has probably been touched in some way by a mechanical engineer.

What is the Mechanical Engineer?

01-mechanical-engineer-technology

Mechanical engineering is a broad field of engineering that involves the use of physical principles for analysis, design, manufacture and maintenance of mechanical systems. Traditionally, it has been the branch of engineering that through the application of physical principles has enabled the creation of useful devices, as tools and machines.

Mechanical engineers use principles such as heat, force and the conservation of mass and energy to analyze static and dynamic physical systems, helping to design objects. Mechanical Engineering is the branch of machinery, equipment and facilities bearing in mind ecological and economic aspects for the benefit of society. To do their job, mechanical engineering analyze needs, formulate and solve technical problems through an interdisciplinary, and relies on scientific developments, translating into elements, machines, equipment and facilities to provide adequate service through the rational use and efficient use of available resources.

01-mechanical engineer-technology-projects

Engineering is dedicated to designing, building, negotiation and component maintenance. It required new devices with complex functions in the movement or that withstand large forces, so it was necessary that this new discipline to study the movement and balance. It was also necessary to find a new way of running the machines as originally used by human or animal power. The use of machines that run on energy from the steam, coal, gas and electricity brought great progress.

Pilot to Mechanical engineer-the story so far.

August 23, 2011

“What do you want to become when you grow up, a doctor or an engineer?” asked my grandpa when I was a four year old. A question that evolved from a typical malayali mindset. Most of the mallu kids are taught to reply either doctor or engineer if somebody asks. My answer was pilot. A couple of trips to Trivandrum airport and my favorite toy aeroplane might have struck the spark in me. The ‘pilot bug’ gradually died down as it was replaced by police,inspired by some action movies.


I imitating a policeman ( Cops never aim & salute simultaneously :-P)

Quite ironically another movie which I saw when I was 7-8 years old, made me quit the desire to become a policeman. The movie was ‘Nanma niranjavan sreenivasan’ ( a Malayalam movie, Jayaram starrer). The hero of the movie was a police constable and in one particular incident the hero had to guard a deadbody, alone throughout a night. The next morning he was shivering with fever. That scene made an impact on my ‘weak heart’.

I fell in love with science @ school in 3rd or 4th standard. I dreamt of becoming a scientist . I stood odd in my class when teachers asked about ambition. The funniest part of ‘scientist story’ was that I did some experiments hoping serendipity.I still remember trying to burn various shrubs and grasses to discover biofuels when the hyped story of Ramar Pillai’s biopetrol was at its peak. Though I wanted to become a scientist, my mind wandered between astronomy, biology and geology.

I wrote the entrance exam for admission in Sainik school (9th std) and got shortlisted for the interview and medical checkup. To be frank I was more interested in the discipline , the sports and games and the huge campus, than becoming a defense personnel. The ‘scientist bug’ didn’t leave me. It was time for the interview and I had to strike a balance between ‘scientist’ and ‘defense personnel’. The interview panel consisted of three people, all of them defense staff. They shot the ‘ambition question’ and my answer was scientist in defense sector. They asked ” what do you mean ?” . I answered ” just like A.P.J Abdul Kalam”. Pokhran II and my interview happened in the same week and I went not stop about fission, fusion etc. They asked “what will you do if you don’t become a scientist?”. I replied ” I will join the defense services”. It didn’t convince them and finally I didn’t make it. They were interested in future soldiers, not scientists.

My grandpa’s question again came back when I finished 10th standard. This time from my parents. I changed my mind to engineer from scientist, but my parents wanted me to become a doctor( guess they were attracted by the social status and moreover my grandpa’s wish). I was in a reluctant mood , wrote the medical entrance and ended up in failure. After that I went for 1 year medical entrance coaching at a reputed coaching center . I neither gave 100% commitment to it nor dishearten my parents by saying a ‘no’ to the medical stream. I couldn’t get enough rank the second time also. The truth was that I often went in a ‘stealth mode’ practicing some maths problems which helped me fetch a fair rank in engineering entrance exam. Now there weren’t many options left other than joining bachelors degree course in engineering. I never blame my parents for the ‘lost’ 1 year, In fact I say I am responsible for the good or the bad that happen in my life.I should have taken a bold step. People (friends, relatives etc.) call it ‘lost’ year , but I never felt so and moreover learnt a couple of lessons in life.

Now it was time to choose the branch of engineering. The general trend was choosing electronics and communication . I was also in the mood until I got enlightened about Mechanical engineering by Dr. S. Jose , my relative and academic guru. Himself being a Mechanical engineer and Asst Professor, threw insight to the various aspects of mechanical engineering and I never thought twice to choose my stream. Mechanical engineering, being a ‘broad’ stream of engineering rendered me numerous options to choose- energy sector,oil and gas ,automobiles, aeronautical, aerospace,thermal.

I never had an interest in computer programming. I still remember, how tough the C++ programming was in 3rd semester for me, just managed to fetch a pass in that subject. 90% of the companies which came to my college for campus recruitment were IT companies. All the placement activities started in 7th semester. Though I wasn’t interested, just for the sake of attending tests and interviews, I participated in the drives. 3-4 companies came and I didn’t manage to get 1. Finally I got a job in a reputed IT company .I never wanted to join that company and told my intentions to parents. They advised it will be utter foolishness if I don’t join the IT firm, without having another job in hand. I was mentally preparing for a fight with them, thought of firing all guns to get a job in core field. I continued writing exams and attending interviews, and got a job in one of the fields which I dreamt of getting into- Oil & gas industry.My parents were happier than me. Thanks to all. Presently, striving hard to achieve my goals, and will be writing a part 2 to this post some years later. 🙂
