Laminar Viscosity
 
Hi,

Could someone please explain what laminar viscosity is, is it the same as kinematic viscosity, if not what is their relationship?

Many thanks
Dave

The term laminar viscosity may refer to either the kinematic or dynamic viscosity of the fluid, and is used to delineate the fluid viscosity (a fluid property) from the eddy viscosity in turbulence models. The eddy viscosity is not a property of the fluid, but can be considered as a property of the flow.

When using the MACRO C_MU_L(c,t) in a UDF, will it return the kinematic or dynamic viscosity?

Dynamic viscosity.
