Abstract As an approach to analyses 3D complex flow field,Computational Fluid Dynamics(CFD) has been widely applied in pump design and analysis.It can be used to study the features of pump energy transfer and cavitation,predict pump operation characteristics,and optimize pump hydraulic design.This paper describes the details of pump CFD analysis including the mathematical model of pump CFD,mesh and numerical scheme,turbulence model,function and limitation of CFD,etc.Validation and verification of CFD are discussed according to the latest relative standards.The current situation and development trend of pump CFD are also presented.
