Combined Geometric Approach for Solving the Navier-Stokes Equations on DynamicGrids

摘要

A combined geometric approach for solving the Navier-Stokes equations ispresented for the analysis of planar, unsteady flow about mechanisms with components in moderate relative motion. The approach emphasizes the relationships between the geometry model, grid, and flow model for the benefit of the total dynamics problem. One application is the analysis of the restart operation of a variable-geometry, high-speed inlet.
