Does the TKE computed from a turbulence model (or Reynolds stress tensor) Code: k_turb = 0.5(R_11 + R_22 + R_33) include the unsteady Reynolds-averaged U, or do these need to be combined before comparing to experiment, e.g.: Code: k = k_turb + 0.5(var(U) + var(V) + var(W)) __________________ Home \| Twitter \| GitHub
