Hi,
I want to induce a k+ equation in UDF for improving k+ vs y+ profile for a channel flow. I have not idea how to do it in Fluent software. Can anyone please help? The formula is k+ = B y+^2 e^(-y+/A) where B = f(Re_tau) and values are available for B at some Re_Tau . A= 8 Re_tau= u_tau (channel height)/nu, U_tau = sqrt(Tau/rho) . I am new to UDF that is why need your help guys. Regards, |
