hit New Member WANG Join Date: Oct 2009 Posts: 1 Rep Power: 0	Dear CFD friends, now,I have a question about calculation of compressible flow at low mach,But I can not get a good result.I can not find reasons. Calculation condition as follows: [1]stream flow Mach number M=0.01 [2]Rey=6e4 [3]space: MUSCL method Roe average method [4]time: LUSGS method [5]Laminar flow method(Compressible flow Code is used) By these conditions,for example,If Roe-average method is used at very low Mach number(Mach number M=0.01) by Compressible flow Code,Can I get good result? Thanks
