Unformatted text preview: cid flow is one where the viscosity is negligible. It could be because the fluid’s viscosity is very small, or it could be because is very small. A viscous flow is one where the viscosity is not negligible. In many cases that interest us in this course, the only place where is big enough to matter is in a thin boundary layer around a body, and in the wake immediately downstream of the body. For these cases we can to a great deal of analysis on the flow outside the boundary layer using equations and methods that only work for inviscid flows. These equations are much simpler than the full viscous flow equations. Figures from Anderson, Fund Aero. Some cases where the inviscid aproximation doesn’t w...
