Design and Realization of the Computer Simulation Platform of Multi-Dimensional Models for In-Cylinder Process of Engine

This study investigated the design of the simulation software for in-cylinder process of internal combustion engine.First,The multi-dimensional model was constructed by integrating such sub-models as spray,combustion,soot,etc.into the model of in-cylinder CFD.Second,Double Precision System(DPS) of Compaq Visual Fortran was set and the KIVA-3V code was compiled by means of PC computer.Third,a special module was designed and integrated in KIVA-3V code for visualizing the solution by AutoCAD.Finally,the discussion was demonstrated by comparing and analyzing the predicted and measured results after simulating and testing Caterpillar3406 diesel engine.The results showed that a huge number of data,figures and curves connecting with thermodynamics,emissions,as well as combustion procedure were obtained.It has been concluded that the software of multidimensional models for in-cylinder Process of Engine is workable,and can be applied to the internal combustion engine industry.
