==== 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
            
<note tip>
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. \\
