| Abstract: | The multi-physics field,which comprises of flow, temperature and stress field for a diesel engine,is simulated in this paper applying modern design methods.The purpose is to explore the general methods and concrete implementing techniques for the engines' coupling analysis of flow field,temperature field and stress field.The influence of several key structure dimensions and structure types of the cylinder head on temperature field and stress field is studied,and an analysis of their sensitivity about flow quantity to cylinder head temperature is carried out. |
