Research progress on automated CFD technology for viscous flow
For the automated solution of Euler's equation,there are mature CFD commercial software at home and abroad,such as Cart3D,KARALIT CFD,Pi-Flow,etc.However,for the automated CFD calculation of NS equation,there are still a lot of technical difficulties,which is still in the initial stage.On the basis of literature research,the functional and technical characteristics of automated CFD software based on Cartesian grids are summarised,and the research progress of object surface boundary processing method and viscous flow simulation technology under Cartesian grids are introduced.On the basis of analysing the deficiencies of the above technical routes,a new framework applicable to automated CFD calculation of viscous flow is proposed based on the team's research results,and the key technologies involved are introduced.Numerical tests show that the proposed new framework has the prospect of engineering applications for automated solution of viscous flows.
