what is the difference for the below three variable, which should be choose when I simulate ? is the dynamic viscosity or kinematic viscosity ?

C_MU_L(c,t)->laminar viscosity

C_MU_T(c,t)->turbulent viscosity

C_MU_EFF(c,t)->effective viscosity

Effective viscosity is the sum of laminar and turbulent viscosity. Turbulent viscosity is turbulent viscosity. Laminar viscosity is dynamic viscosity.

when do we use the three viscosity, if it is laminar flow, we use the laminar viscosity? if it is turbulent flow, we use the turbulent viscosity? all the three are dynamic viscosity?
