Simulation of Gas Flow Through Engine

Abstract

Modern diesel engine has to meet both legislative and customer requirements simultaneously. Engine sub-systems are required to be precisely matched considering their interactive effect. It is a costly and time-consuming task if done experimentally. This task is becoming more complex due to flexibility in the advanced subsystems, which makes optimum matching of the subsystems practically becomes impossible. Use of simulation tools is very effective to handle this complexity and has advantage of significantly lower development time and cost. 3D CFD and 1D thermodynamic simulation tools are effectively used to analyse and tune engine subsystems performance. This gives opportunity to tune sub-system performance with their interactive effects, without a need of making physical prototypes. Considering the execution time, 1D thermodynamic simulation tool is more useful in the early stage development of the engine.
