Boundary integral equations and conservative dissipation schemes for full potential transonic flows (Q1312581)

A boundary integral formulation for the nonlinear aerodynamic analysis of three-dimensional full potential transonic flows is presented. The emphasis is on the analysis of the effects on the solution of artificial dissipation schemes, which are necessary in order to capture properly the physics of the phenomenon. The main novelty is the use of conservative schemes, never previously used in boundary integral formulations where all the existing approaches are based on non-conservative ones. Specifically, a linear dissipation term is added directly to the continuity equation: hence the name artificial mass-generation scheme.
