get the value of six Reynolds Stress components?
 
Hello,all.I am using CFX for turbomachine calculation. I want to get the value of six reynolds stress components but not using the turbulence model of RSM or ASM ,in stead , i use other models such as kw, sst-kw,etc. Is is possible for me to get the six reynolds stress component? in whatever ways Thank you in advance. July

Hi,

You can work out the Reynolds stresses from a k-e or k-w simulation result. Have a look at "Turbulence Modelling for CFD" by Wilcox or any other turbulence modelling textbook.

Note that for the two equation turbulence models are isotropic so the normal Reynolds stresses are equal and the cross terms are zero.
