Consistent Strongly Implicit Iterative Procedures for Two-Dimensional Unsteady and Three-Dimensional Space-Marching Flow Calculations

摘要

First and second-order accurate the consistent versions of the coupled strongly implicit procedure (CSIP) have been developed and investigated for diffusion, potential flow and reduced Navier-Strokes (RNS equations. Typical examples for the flow over an airfoil and a flat plate at incidence are presented. The method is also applicable to space marching for 3-D flows. Primitive variable forms of the (RNS) and the boundary region equations are considered for low speed flow near the trailing edge of a finite-span plate for supersonic flow over a cone at incidence, respectively. The composite velocity formulation is considered for flow over a cylinder of rectangular cross-section.
