An hp‐adaptive unstructured finite volume solver for compressible flows

摘要: Summary The idea of hp-adaptation, which has originally been developed for compact schemes (such as finite element methods), suggests an adaptation scheme using a mixture mesh refinement and order enrichment based on the smoothness solution to obtain accurate efficiently. In this paper, we develop hp-adaptation framework unstructured volume methods residual- adjoint-based error indicators. For residual-based indicator, employ higher-order discrete operator estimate truncation error, whereas is weighted by adjoint problem output interest form indicator adaptations. We perform our local subdivision cells with non-conforming interfaces allowed reconstruction polynomials approximations. present results two-dimensional compressible flow problems including subsonic inviscid, transonic laminar around NACA 0012 airfoil also turbulent over flat plate. Our numerical suggest efficiency accuracy advantages hp-adaptations uniform flows without singularities. This article protected copyright. All rights reserved.
