Evaluation of a WENO method in implicit Large Eddy Simulation of circular cylinder flow

Implicit LES results of a cylinder flow with high order numerical methods in a coarse and a refined grid were compared. The weighted essentially non-oscillatory (WENO) scheme is employed for convective flux while central differencing schemes are used for viscous terms. Several modifications were made to the high order accuracy scheme. Results show that the high order accurate schemes adopted in this paper is feasible and efficient.
