Studies of Wings Supporting Non-unique Solutions in Transonic Flows
Wings Supporting Non-unique Solutions Transonic Flows
2015/7/6
Non-unique numerical solutions of transonic flows over airfoils have been found, first for potential flow equation, and later for Euler and RANS equations. The studies have also been...
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....
