ABSTRACT

For certain viscous §ow problems, it is not possible to obtain an accurate solution using the simpli-ƒed §ow equations discussed in Chapters 6 through 8. Examples of such §ow problems include shock-boundary-layer interactions, leading edge §ows, certain wake §ows, and other §ows that involve strong viscous-inviscid interactions with large separated §ow regions. For these cases, it becomes necessary to solve the complete set of Navier-Stokes equations (or the Reynolds averaged form of these equations). Unfortunately, these equations are very complex and require a substantial amount of computer time and storage in order to obtain a solution. However, if the §ow is incompressible, the equations can be simpliƒed, and the required computer time is often less.
