Implicit Large Eddy Simulation of weakly-compressible turbulent channel flow
We present a comprehensive investigation of high-order Implicit Large Eddy Simulations in weakly compressible and turbulent channel flow. We show that low-Mach corrections significantly improve the accuracy of 2nd to 5th order ILES schemes. The WENO 9th-order scheme provides the best accuracy without using low Mach corrections. Detailed data for the accuracy vs associated computational cost for each ILES method are presented.
