Prediction of Heat Release Rate and Engine Emissions Using an Unsteady Flamelet Model Approach for a Compression Ignition Engine

AbstractDiesel Unsteady Flamelet Model (DUFM) approach along with probability density function (PDF) has been used to investigate the eï¬€ect of breakup length on the in-cylinder pressure and the rate of heat release. Two spray breakup models, WAVE and Kelvin-Helmohltz Rayleigh Taylor (KHRT), have been investigated by varying the magnitude of the breakup constants. The optimized set of parameters are used to predict the in-cylinder pressure, the rate of heat release and NOx emissions in a direct injection (DI) engine. A chemical mechanism of n-heptane with 29 species and 52 reactions has been used.
