Namelist "Temperature_Initialization"

This data setup is used to define the initial temperature field over the domain.

Full data set of the namelist

 &Temperature_Initialization Temperature_Reference_Value    = 293.0,
                             Initial_Field_Option_For_Temperature= 0 , 
                             White_Noise_Magnitude_For_Temperature= 0.0 /
For low Mach-number flows, the user must ensure the coherence between the reference values of physical quantities defined in the namelist "Fluid_Properties" (temperature, density and molecular mass), the initial temperature field over the domain (defined here) and, if needed, the species mass fraction distribution defined in the namelist "Species_Initialization" (if the gas is composed with multi-components).
Keep in mind that the reference value of thermodynamic pressure is calculated from the reference values of temperature, density and molecular mass of the fluid (see namelist "Fluid_Properties").
The density field is then initialized from the fields of temperature (and species mass fractions if needed) by considering that the thermodynamic pressure is uniform over the domain (low Mach-number hypothesis).

Definition of the data set


Temperature_Reference_Value

  • Type : real value
  • Reference temperature value.

Initial_Field_Option_For_Temperature

  • Type : integer value
  • Option to define the distribution of the temperature over the domain :
    • 0 : Uniform distribution
    • 1 or greater : Optional values associated to temperature field defined by the users in the appropriate fortran module (see module_user_define_init_fields.f90). The reference value can be used to define the temperature scale.

White_Noise_Magnitude_For_Temperature

  • Type : real value
  • Magnitude of the white noise on the temperature field.
  • The magnitude is defined as a fraction of the local value in each cell ( i.e. 0.4 corresponds to 40% of the local value of temperature on the grid)
