主 题:Adaptive mesh refinement Flux reconstruction Positivity-preserving scheme Robustness Shock-capturing
摘 要:In this paper,a simple and robust shock-capturing method is developed for the Flux Reconstruction(FR)framework by combining the Adaptive Mesh Refinement(AMR)technique with the positivity-preserving *** adaptive technique avoids the use of redundant meshes in smooth regions,while the positivity-preserving property makes the solver capable of providing numerical solutions with physical *** compatibility of these two significant features relies on a novel limiter designed for mesh *** ensures the positivity of solutions on all newly created ***,the proposed method is completely positivity-preserving and thus highly *** performs well in solving challenging problems on highly refined meshes and allows the transition of cells at different levels to be completed within a very short *** performance of the proposed method is examined in various numerical *** solving Euler equations,the technique of Local Artificial Diffusivity(LAD)is additionally coupled to damp *** importantly,when solving Navier-Stokes equations,the proposed method requires no auxiliaries and can provide satisfying numerical solutions *** implementation of the method becomes rather simple.
