Finite element analyses of secondary flow problems

Abstract

A method is presented for the determination of secondary flow fields in three practical examples. In one, the flow is laminar and the other two turbulent. The latter were analysed using a one‐equation or two‐equation model of turbulence in conjunction with the equations of motion. Methods of improving the boundary condition for secondary flow prediction by introducing a ‘slip’ condition at near wall locations are referred to, and its effect demonstrated. Finally, a fluid film of extremely high aspect ratio and in laminar motion was investigated and the existence of recirculatory flow pockets predicted.
