AO4010 Combustion in Jet and Rocket Engines Syllabus – Anna University PG Syllabus Regulation 2021
COURSE OBJECTIVES:
1. This course provides the basic principles of combustion, types of flames and also familiarizes the combustion process in gas turbine, ramjet, scram jet and rocket engines.
2. This course explains the concept of thermochemistry, enthalpy, adiabatic flame temperature, combustion products and their application to combustion related problems.
3. This course presents the concept of chemical rates of reaction, collision theory and Arrhenius equation for analysing the different types of reactions.
4. This course gives an idea to compare the properties and characteristics of different type of flames and apply the same to combustion phenomenon in rocket motors and its exhaust.
5. This course also imparts knowledge to interpret the various combustion processes that take place inchemical rockets.
