OAE751

FUNDAMENTALS OF COMBUSTION

 LPTC

3003

OBJECTIVE:
To make the student understand the fundamentals of combustion and to teach them combustion in different regions like basic flame to gas turbine engines to rocket engines and finally how it is done in supersonic speeds.

UNIT I

INTRODUCTION TO COMBUSTION

9

Thermo-chemical equations –Heat of formation –Activation energy -Multi-step reactions - Heat of reaction -first order, second order and third order reactions – Calculation of adiabatic flame temperature

UNIT II

BASICS OF CHEMICAL KINETICS AND FLAMES

9

Premixed flames –Diffusion flames –measurement of burning velocity – various methods –Effect of various parameters on burning velocity – flame stability –Deflagration – Detonation – Rankine- Hugoniot curve –Radiation by flames.


UNIT III

COMBUSTION IN GAS TURBINE ENGINES

9

Combustion in gas turbine combustion chambers -Recirculation – combustion efficiency, Factors affecting combustion efficiency-Fuels used for gas turbine combustion chambers – combustion stability –Flame holder types.

UNIT IV

COMBUSTION IN ROCKETS

9

Solid propellant grain types – types of solid propellant burning in rocket combustion chambers – basic mechanism of composite propellant combustion – solid propellant burn rate laws – criterion for stable combustion - combustion in liquid rocket engines – single fuel droplet combustion model – combustion in hybrid rockets.

UNIT V

SUPERSONIC COMBUSTION (Qualitative Treatment only)

9

Introduction – supersonic combustion controlled by diffusion, mixing and heat convection – Analysis of reactions and mixing processes - supersonic burning with detonation shocks .

TOTAL : 45 PERIODS

OUTCOMES:
• The student will be in a position to understand the detailed mechanism of Aerospace Vehicles and Aircraft Engines.
• The student will be able to analyse and impart the combustion processes that occur in Aircraft Engines and Rocket Vehicles.
