Abstract : To develop new, physically-motivated approaches for simulation of 3D incompressible vortical flows. Methods are expected to conform sharply to geometrical and physical structures, and the application of fundamental interest is the formation and evolution of wingtip vortices. The discretizations should base on variational multiscale principles, admit efficient algebraic solution strategies, and be amenable to numerical analysis. Presenting such analysis, as well as numerical validations, is also within the objectives.
