英文摘要：

With the rapid development of computer technology,computational fluid dynamics has been widely used in the numerical simulation of flow field in heart and some valuable relevant outcomes has been obtained.CFD is playing an increasingly important role in the study of cardiac function. Currently,it has become an important research in basic and clinical cardiovascular research areas in which CFD is used to simulate and analyze fluid dynamics and flow field in heart,which is important for prevention,diagnosis and treatment of the cardiovascular disease. In this paper,we describe the development of numerical simulation of flow field within left ventricular based on CFD,the research status and classification method. We summarize the main issues of numerical simulation of flow field within left ventricular based on CFD and put forward the future direction of this research field.
