Program FINSUP: Steady and Unsteady Supersonic Flow in Cascades by a Finite Element Method

摘要

This program calculates steady and unsteady supersonic flow in cascades using a finite element method. The program runs in three sections. The first section generates the mesh, the second section calculates the steady flow through the cascade, and the third section calculates unsteady pressure distributions, force coefficients and moment coefficients due to translational and torsional motion of the blades. These sections are linked by a control program written in Phoenix. Since the program assumes potential flow it cannot deal with wakes coming from upstream and shock waves are smeared. Flow round the leading edges of thick blades is correctly handled, and the program also allows for acoustic waves propagated upstream and downstream.
