Simulation and Modeling of Compression Stroke in Diesel Engines

Abstract:

The objective of this study is to simulate the compression stroke in diesel engines by using computational fluid dynamics (CFD), and to model the compression stroke by using thermodynamic equations for Ideal gases and polynomial function that fits thermodynamic data of JANAF tables. The most important parameters to be simulated and modeled during the compression stroke are temperature and pressure of cylinder gases because of their important effects on mixture formation inside the engine combustion chamber. The simulation part will be performed using ANSYS ICE software. The modeling part will be performed using a MATLAB program composed by the corresponding author. Simulation and modeling process will be carried out between the intake valve close (IVC) and top dead center (TDC), the results of simulation and modeling will be compared and discussed.
