220.127.116.11 Newtonian Fluid
The material type for a Newtonian fluid is “Newtonian fluid”. The following material parameters must be defined:
|<mu>||shear viscosity||[P t]|
|<kappa>||bulk viscosity||[P t]|
The viscous shear stress for this material model is Stokes' condition is a constitutive assumption that sets , implying that . This assumption is only valid for some fluids (e.g., monoatomic gas ). Users may use or ignore this assumption by selecting an appropriate value for .
