Development & Application of Computer Simulation Platform of Multi-Dimensional Models for In-cylinder Flow Calculation of Engine

AbstrcatThis study investigates the design of simulation software for in-cylinder flow process of inter combustion engine. Precision of the platform is improved by the application of multi- dimensional models of in-cylinder CFD. Then, FDM(Finite Difference Method)and DPS(Double Precision System)of FORTRAN are contributed to code design in order to enhance solution velocity and capability of PC. Moreover, a special module is attached to the code for visualizing the solution in CAD.The test shows that the platform can accurately be used to simulateflow process and effects caused by physical factors, to provide the next combustion simulation with flow data and to predict emissions. It should be recommended in the field of engine.
