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.</em>}, number={1}, journal={Journal of the Pakistan Institute of Chemical Engineers}, author={Imran, S. and Noor, F. and Shad, R. and Anwar, Z. and Hussain, A.}, year={2015}, month={Mar.}, pages={21–36} }
