The physical properties for an incompressible fluid without multi-species components

We report here the dimensionless data set about the fluid properties defined above.

&Fluid_Properties Variable_Density = .false. , !---- Incompressible fluid
Constant_Mass_Flow = .true. , !---- The mass flowrate is constant
Heat_Transfer_Flow = .true. , !---- Heat transfer enabled
Reference_Density = 1.0 , !---- Dimensionless fluid density
Reference_Dynamic_Viscosity = 1.D-02 , !---- Dimensionless dynamic viscosity (=1/Reh)
Reference_Temperature = 1.0 , !---- Dimensionless reference temperature (=Tc*)
Prandtl = 0.71 , !---- Prandtl number value
Thermal_Expansion_Coefficient= 1.0 / !---- Dimensionless thermal expansion coeffficient

The heat capacity of the fluid is not set here because unuseful. For incompressible flows without multi-species components, the enthalpy equation is reduced to an advective-diffusive transport equation for temperature. Only the thermal must be defined which is directly computed from the “Reference_Dynamic_Viscosity”, the “Reference_Density” and the “Prandtl” values.
