Dear OpenFOAMers,
I am working on RANS with combustion involved. I need to define a mut file. In the mut file, I need to use a wall function called "mutWallFunction". There are some parameters that I need to define. They are: Cmu, kappa and E. I know that Cmu is 0.09, it is the turbulence viscosity coefficient. kappa is the Von Karman's constant, which is generally 0.41. But how about E? What is E, and in the files, it is generally 9.8. I am sure why and what E is. Thank you very much Best Regards Litchy |
