Hello,
Looking at the values of the "Eddy_Viscosity" variable in a (tecplot ascii format) field output of a RANS SA calculation (SU2 v7.0.6), I wondered if this variable should be interpreted as a dynamic or kinematic viscosity . Does anybody know?
Thanks in advance,
Gérald

SA solves a transport equation for the kinematic turbulent eddy viscosity. The effective viscosity is then the sum of the regular kinematic viscosity and the turbulent viscosity. When the flow is turbulent, the turbulent eddy viscosity almost always dominates and the 'laminar' kinematic viscosity is often negligible. See also:
