Description
Summary:Formulation and results of a CFD code for internal combustion engine are given in the paper. The CFD code, developed in-house, has proved helpful in studying the flow patterns like swirl, squish, tumble, and turbulence generation. Through numerical tracing of mass less particles, good idea about the possible stratification patterns is obtained. For GDI engines, where a very specific stratification pattern is required, geometry optimization is required. This code has proven useful in this regard. Results for two different configurations show that some changes in combustion chamber geometries prove helpful in achieving desired stratification patterns. This exercise would have taken huge efforts and resources, if done experimentally.
