Th. Ramin et Rh. Pletcher, DEVELOPMENTS ON AN UNSTEADY BOUNDARY-LAYER ANALYSIS - INTERNAL AND EXTERNAL FLOWS, Numerical heat transfer. Part B, Fundamentals, 23(3), 1993, pp. 289-307
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 appli
cable to both internal and external unsteady flows. Example results de
monstrate advantages of using a non-Cartesian grid for external flows.
Boundary-layer solutions were reported for the first time for a numbe
r 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 agree
ment with data available in the literature.
