BEST MECHANICAL ENGINEERING SEMINARS

Hello friends,
Here I want to discuss some best mechanical engineering seminars. As we know seminars are most important thing for UG or PG courses. Each and everyone should take at-least one seminar during their course time. I hope it will be helpful to your final year seminar.

1. A Study on Automobile Differential System

2. Study of heat pipes

3. A Study on Thermo-Acoustic Refrigeration System

4.Study on Paper Battery

5. Study on SHOT PEENING

6. Under Water Welding

7. CATALYTIC CONVERTER FOR AUTOMOBILE

CATALYTIC CONVERTER FOR AUTOMOBILE

CHAPTER 1 INTRODUCTION Air pollution generated from mobile sources such as automobiles contributes major air quality problems in rural as well as in urban and industrial areas in both developed and developing countries. Vehicle population is projected to grow close to 1300 million by the year 2030. A large amount of vehicle transportation relies on combustion of diesel, gasoline, jet fuels with large amount of emission of carbon monoxide (CO), Unburned hydrocarbons (HC), Nitrogen oxide (NOx) and particulate matters (PM) are specially concern. HC, CO occur because the combustion efficiency < 100%. The NOx is formed during the very high temperatures (>1500 C) of the combustion process resulting in thermal fixation of nitrogen in the air which forms NOx. Typical exhaust gases compositionat the normal engine operating conditions are: Carbon monoxide (CO, 0.5 Vol. %), unburned Hydrocarbon (HC, 350vppm), Nitrogen Oxides (NOx, 900ppm), Hydrogen (H2, 0.17vol. %), Water (H2O,1...

A Study on Thermo-Acoustic Refrigeration System

IINTRODUCTION Refrigeration is the science of producing and maintaining temperatures below that of the surrounding atmosphere. It finds application in almost all fields for the purpose of temperature control. Until the beginning of the twenty-first century, CFC’S were widely used as refrigerants. The use of CFC’s is banned acknowledging its harmful effects on the environment. This led to the evolution of HCFC’s and HFC’s. However these too have disadvantages. Both have high cost of production and contribute to global warming. The development of alternative cheap and green refrigeration techniques has thus become the priority for the future. Thermo Acoustic Refrigeration (TAR) is one such green idea for refrigeration. Lord Rayleigh [1] was the first to give a thoroughly qualitative description of thermo-acoustic effects in 1887. After this, the subject remained untouched until 1970 when scientists like Rott, Hofler and G. W. Swift signaled its revi...

UNDER WATER WELDING

INTRODUCTION Welding is an important process of modern engineering – in all branches. It is used in fabrications and erections in infrastructures and installations. It joins metals or thermoplastics. Forming a pool of molten mass, the weld puddle, and allowing it to cool to become a strong joint is the basis of the process of welding. For repairing to be carried out underwater, there is a separate process. That is called underwater welding. If damaged ships are to be repaired, underwater welding is the basic technology to be used. It is a highly-specialized profession – more employed in the oil or shipping industry and also in the defense operations. The fact that electric arc could operate was known for over a 100 years. The first ever underwater welding was carried out by British Admiralty – Dockyard for sealing leaking ship rivets bel...
