ME 306 Applied Thermodynamics

Course Code/Name: ME 306 Applied ThermodynamicsCourse Contents:

  1. Compressible fluid flow. Sonic velocity. Isentropic flow. Normal shock.
  2. Psychrometry. Basic properties, tables, charts. Psychrometric processes.
  3. Combustion. Fuels. Stoichiometry. Heat of reaction. Adiabatic flame temperatue.
  4. Energy conversion cycles. Introduction, thermodynamic basis. Performance parameters.
  5. Cycles and their implementation for power generation and refrigeration.

 

Course Description and Motivation:
While the first course in thermodynamics (ME 209) was more or less a revision of the topics already covered in the JEE, this the first course that gives you a “working feel” of the subject. This course forms the basis for all further TFE courses to build upon. Those being – Steam and Gas turbines, Refrigeration and Air-Conditioning, IC Engines etc. One can fully understand and appreciate these courses better after a thorough study of Applied Thermodynamics.

After this course, one can identify the different components/steps that comprise any power or refrigeration system and understand their working principle and significance.

To state simply, one can understand how petrol engines, diesel engines, steam engines and jet engines differ from one another in working principle and structure. One can understand the difference between reciprocating engines and turbines, their advantages-disadvantages and typical areas of application.

The study of refrigeration systems will leave one with a good idea of the different components in a household refrigerator and their function. One will also learn different methods of increasing their efficiency via intercooling/reheating.

While everyone has a fair intuitive understanding, that dry air is easier to cool as opposed to moist air, the study of psychrometry in this course will allow one to define, quantify and calculate the  cooling effectiveness of different systems with changing humidity. You will understand better why swamp coolers are more effective in dry places like Rajasthan and useless in hot and humid Mumbai.

Useful resources:
While it is a good practice to refer to textbooks or video lectures besides your class notes, it is also important to remember that these sources may not be flawless. Reference material should only be used as a tool to strengthen concepts and not as a substitute for your class notes.
