backscatter Member Anonymous Join Date: Aug 2016 Posts: 75 Rep Power: 9	Hi, I was reading up some material on low Re kEpsilon model and I observed that many versions of the Launder Sharma damping function exist differing in its coefficients. For example, one version I saw reads, $f_{\mu }= exp(-3.4/(1+R_T/50)^2)$ and the other, slightly different version reads, $f_{\mu }= exp(-2.5/(1+R_T/50)^2)$ Is it normal for people to adjust its coefficients?
