AE214: Thermodynamics
Description: The course Thermodynamics starts with the basic principle which we already were familiar during JEE times. Later it uses these principles to understand the working of different kind of engines cycle which gives a feel of aerospace and more specifically Aircraft propulsion.

Course Contents:
The course instructor for this course has been Prof. Sudarshan Kumar. Following is the basic outline of the course:
Basic concepts: System boundary, surroundings, state, extensive and intensive properties, energy interactions, work and heat transfers, equilibrium, quasi-static and reversible processes, non-equilibrium and irreversible processes.
Thermodynamic laws: Zeroth law and temperature, first law and internal energy, first law applied to flow processes, second law, entropy and absolute temperature, third law and absolute entropy, thermodynamics of simple compressible systems, energy and exergy.
Applications: Closed and open systems, polytropic processes, cyclic processes, Carnot cycle; Cycle analysis: Otto cycle, Diesel cycle, Joule-Brayton cycle; ideal and real cycles, design point analysis.
Special topics: Elements of heat transfer and combustion, isentropic flow, flow with friction and heat transfer.
Introduction to aerospace power plants: Piston prop, turboprop, turbojet, turbofan, turbo shaft, ramjet, scramjet, rockets.
Motivation:
Thermodynamics has a direct application in many fields like Aerospace (gas-engines), Chemical and chemistry (in chemical reactions and statistical thermodynamics), Mechanical (for study of turbines, compressors). This course is also pre-requisite for many other courses such as
- Aerospace Propulsion
- Compressor and Turbines
- Power-Plant design of Aircraft
- Aircraft Design
- Aircraft Propulsion Laboratory
Text Books:
Mostly the basic idea gets clear from the classroom lecture slides but to gain on extra information these books should be preferred.
