Default turbulence decision???

Hello everybody. I am simulating a hypersonic flow problem over a wedge shaped body and many other bodies. when i opted "laminar"case, it showed the error that "reynolds number is very high" and coverges suddenly to a wrong value. Then I switched on to Turbulence K-e model(medium 5%), then I got the correct results. But for K-e model with "1% or 10%above" I was unable to obtain the correct results. Can any one explain what acually happened ??? (I have standard results to compare) Thanks in advance. Regards VVJ

Best go and read a book on turbulence modelling I'm afraid, as it would take too long to explain why on this site.
