On the prediction of highly vortical flows using an Euler equation model, part 2
Abstract
An investigation of the power of the Euler equations in the prediction of conical separated flows is presented. These equations are solved numerically for the highly vortical supersonic flow about simple bodies. Two sources of vorticity are studied: the first is the flow field shock system and the second is the vorticity shed into the flow field from a separating boundary layer. Both sources of vorticity are found to produce separation and vortices. In the case of shed vorticity, the surface point from which the vorticity is shed (i.e., separation point) is determined empirically. At very high angles of attack the only stable separated solution is found to be asymmetric. Solutions obtained with both sources of vorticity are studied in detail, compared with each other and with potential calculations and experimental data.
