Boundary Integral Equation Method for Unsteady Viscous and Inviscid Flows
A general boundary-element methodology for the analysis of incompressible, unsteady, viscous and inviscid, flows is presented, with emphasis on external flows. The formulations are presented in terms of dynamic pressure; this has the advantage that the field integrals are limited to the region where the vorticity is different from zero. The formulations for viscous and inviscid flows are then compared in order to gain a better physical understanding of the relationship between the two problems. In the process an efficient computational algorithm is developed. Preliminary numerical results are also discussed.
