Computability and adaptivity in CFD
2007 (English)In: Encyclopedia of computational mechanics / [ed] E. Stein, R. de Borst,T.J.R. Hughes, Wiley , 2007Chapter in book (Refereed)
We briefly recall research on adaptive computational methods for laminar compressible and incompressible flow, and then move on to present recent work on computability and adaptivity for turbulent incompressible flow, based on adaptive stabilized Galerkin finite element methods with duality-based a posteriori error control for chosen output quantities of interest, here referred to asgeneral Galerkin G2 methods.
We show in concrete examples that outputs such as mean values in time of drag and lift of turbulent flow around a bluff body are computable on a PC with a tolerance of a few percent using a few hundred thousand mesh points in space.
