Abstract

The objective of this research, is to simulate the in-cylinder mass flow rate for a single cylinder two-stroke spark ignition internal combustion engine. The research describes the Computational Fluid Dynamic (CFD) analysis technique to predict in-cylinder flow on scavenging process. The modeling of three-dimensional solid of scavenging model was developed using Solidwork computer aided design software. The three-dimensional model is imported to the GAMBIT to generate meshes grids and imported to FLUENT software for modeling analysis. This analysis is using the dynamic mesh approaches using unstructured tetrahedral and layered hexahedral elements simulated from Top Dead Center (TDC) at 0 of crank angle. Parameter of pressure is used as boundary condition collected from the experimental results at the intake port. The engine modeling simulates on motored condition for un-firing cases at difference of engine speed. The results shown that, using the dynamic mesh approaches give confident results compared with experimental. The results have been predicted of mass flow rate and mass fraction of burned gases on engine cylinder. Contour plotted of mass fraction burned gases and vector of velocity was plotted.
