Lecture 20 Introduction to FLUENT
上游充通大粤 SHANGHAI JIAO TONG UNIVERSITY CFD Overview Computational fluid dynamics,usually abbreviated as CFD,is a branch of fluid mechanics that uses numerical methods and algorithms to solve and analyze problems that involve fluid flows. CFD software is specifically used for flow analysis and flow field prediction.It can analyze and display phenomena in the flow field.Besides it can predict performance and achieve optimal design results by changing various parameters in a relatively short period of time
