A recently developed multidimensional upwind multigrid method is combined with an adaptive grid refinement strategy in order to provide a numerical technique for computing two-dimensional compressible inviscid steady flows accurately and efficiently. A locally nested sequence of mesh refinements is constructed by a quad-tree data-structure, which easily incorporates the multigrid method using compact-stencil space discretization and explicit multi-stage smoother. Computations of flows through channels and cascades are presented which demonstrate the capabilities of the proposed approach.

Abstract
A recently developed multidimensional upwind multigrid method is combined with an adaptive grid refinement strategy in order to provide a numerical technique for computing two-dimensional compressible inviscid steady flows accurately and efficiently. A locally nested sequence of mesh refinements is constructed by a quad-tree data-structure, which easily incorporates the multigrid method using compact-stencil space discretization and explicit multi-stage smoother. Computations of flows through channels and cascades are presented which demonstrate the capabilities of the proposed approach.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
