Simulation of Non –Evaporating Diesel Sprays and Comparison with Empirical Correlation

Ishtiaq A. Chaudhry, M. R. Mirza, M. J. Rashid


Non-evaporating diesel sprays are simulated using sub models given in Fluent software. Meshing of the CFD model is done using Gambit software before transmitting it to Fluent software. The modeling is carried out using cold bomb conditions under variable gas pressure, density, nozzle diameter and fuel injection pressure, but maintaining gas temperature as atmospheric. The simulated penetration rate and spray tip velocity are compared with existing experimental data. An excellent match is found between simulation results and published correlation. The CFD simulation is found to be highly dependent on injection parameters and operating conditions.
