AU3019 Combustion Thermodynamics and Heat Transfer Syllabus – Anna University Regulation 2021

COURSEOBJECTIVES:

The objective of this course is to make the students to understand the kinetics of combustion and engine heat transfer.

UNIT I THERMODYNAMICS OF COMBUSTION

Combustion process in IC engines-Premixed -diffusion. First and Second Law of Thermodynamics applied to combustion – combustion Stoichiometry- chemical equilibrium- spray formation -droplet combustion.

UNIT II CHEMICAL KINETICS OF COMBUSTION

Combustion kinetics, rate of reaction, equation of Arrhenius, activation energy, Chemical thermodynamic model for Normal Combustion.

UNIT III FLAMES

Laminar – premixed -diffusion flames –flame speed correlations – quenchingflammability.Ignition- flame stabilization- turbulent premixed, diffusion flames – Damkohler number.

UNIT IV HEAT TRANSFER IN IC ENGINES

Engine heat transfer -heat Balance. Measurement of instantaneous heat transfer rate. Heat transfer modelling. Heat transfer coefficients- radiative heat transfer. Temperature measurement in Piston- Cylinder- Cylinder Head-liner- valves.

UNIT V INSTRUMENTATION

Pressure sensors-piezoelectric pickup- crank angle encoder-thermocouples. Hot wire anemometer- laser Doppler anemometry and velocimetry for flow and combustion analysis in IC engines. In- cylinder pressure measurement and Rate of heat release calculation.
