8、libriumWe now perform an order-of-magnitude scaling analysis on the incompressible NS equations. Our goal is to develop a model for the flow in the boundary layer which is less complex than the two-dimensional incompressible NS equations. And, by applying this model, we hope to gain insight into the
9、 fundamental physics at work in boundary layer flows.The mesh is structured and consists of 600 every spaced cells along the surface of the cylinder and 300 cells in the radial direction.In order to test for instabilities to small wavelength disturbances, the grid points were increased from 101 to 5
10、01 points.For this reason, we started our investigation with an analysis of the influence of grid resolution.The speed and altitude ranges of the Space Shuttle and the NASP ascent/descent corridors encompass most such domains.Thus, apart from the fluid dynamic aspect of hypersonic viscous flows, one
