DEVELOPMENTS ON AN UNSTEADY BOUNDARY-LAYER ANALYSIS - INTERNAL AND EXTERNAL FLOWS

A boundary-layer solution Procedure for two-dimensional, compressible unsteady flows has been developed for non-Cartesian generalized grids consistent with first-order boundary-layer theory. The scheme is applicable to both internal and external unsteady flows. Example results demonstrate advantages of using a non-Cartesian grid for external flows. Boundary-layer solutions were reported for the first time for a number of flows that had been computed only by quite different approaches, including the numerical solutions to the Navier-Stokes equations. The results computed for several test cases were found to be in good agreement with data available in the literature.
