Combined Feature-Driven Richardson-Based Adaptive Mesh Refinement for Unsteady Vortical Flows
Combined Feature-Driven Richardson-Based Adaptive Mesh Unsteady Vortical Flows
2015/7/3
An adaptive mesh refinement strategy that couples feature detection with local error estimation is presented. The strategyfirst selects vortical regions for refinement using feature ...
Further Studies of Mesh Refinement: Are Shock-Free Airfoils Truly Shock Free?
Mesh Refi nement Are Shock-Free Airfoils Truly Shock Free
2015/7/3
The Garabedian-Korn airfoil is studied at its inviscid design condition and in the neighborhood thereof. This airfoil was designed with a hodograph method to be shock-free at M = 0.750 and Cl = 0.629....

These comprise a four dimensional coupled space–time set of
nonlinear equations, which need to be solved simultaneously. For
this purpose we introduce a pseudo time derivative term to
equation (2),...
