Hello every body,

In my research i should compare the different RANS models inside a heated pipe. WHen i plot the Turbulent Kinetic energy(k) and the eddy viscosity (mut), every model give me a different profil, and i dont understand why and how in physical part , i did same research and i dont found really a a convincing answer, they just said this modle more apropritey than others but without cited the physical or mathematical raison.

I found that the RSM model dive the higher k but the higher mut was given by the and i dont understand why ??!!

Can you help me pleaaase i really need your help
