If there are outlets, the code will take the center of the ! reference outlet face. ! On the other hand, if we plan to explicitly fix Dirichlet conditions ! for pressure, it is better to indicate to which reference the ! values relate (for a better resolution of reduced pressure). ! Other properties are given by default in all cases. ! Nonetheless, we may note that: ! In the standard case (no gas combustion, coal, electric arcs, ! compressibility): ! --------------------- ! ro0, viscl0 and cp0 ! are useful and represent either the fluid properties if they ! are constant, either simple mean values for the initialization ! if properties are variable and defined in usphyv. ! t0 is not useful ! p0 is useful but is not used in an equation of state. p0 ! is a reference value for the incompressible solver ! which will serve to set the (possible) domain outlet pressure. ! We may also take it as 0 or as a physical value in Pascals. ! With the electric module: ! ------------------------ ! ro0, viscl0 and cp0 ! are useful but simply represent mean initial values; ! the density, molecular dynamic viscosity, and specific ! heat are necessarily defined as fields (whether they are ! physically variable or not): see cs_user_physical_properties ! for the Joule effect ! module and the electric arcs dp_ELE data file. ! t0 is useful an must be in Kelvin (> 0) but represents a simple ! initialization value. ! p0 is useful bu is not used in the equation of state. p0 ! is a reference value for the incompressible solver which ! will be used to calibrate the (possible) outlet pressure ! of the domain. We may take it as zero or as a physical ! value in Pascals. ! With gas combustion: ! -------------------- ! ro0 is not useful (it is automatically recalculated by the ! law of ideal gases from t0 and p0). ! viscl0 is indispensable: it is the molecular dynamic viscosity, ! assumed constant for the fluid. ! cp0 is indispensable: it is the heat capacity, assumed constant, ! (modelization of source terms involving a local Nusselt in ! the Lagrangian module, reference value allowing the ! calculation of a radiative ! (temperature, exchange coefficient) couple). ! t0 is indispensible and must be in Kelvin (> 0). ! p0 is indispensable and must be in Pascal (> 0). ! With pulverized coal: ! --------------------- ! ro0 is not useful (it is automatically recalculated by the ! law of ideal gases from t0 and p0). ! viscl0 is indispensable: it is the molecular dynamic viscosity, ! assumed constant for the fluid (its effect is expected to ! be small compared to turbulent effects). ! cp0 is indispensable: it is the heat capacity, assumed constant, ! (modelization of source terms involving a local Nusselt in ! the coal or Lagrangian module, reference value allowing the ! calculation of a radiative ! (temperature, exchange coefficient) couple). ! t0 is indispensable and must be in Kelvin (> 0). ! p0 is indispensable and must be in Pascal (> 0). ! With compressibility: ! --------------------- ! ro0 is not useful, stricto sensu; nonetheless, as experience ! shows that users often use this variable, it is required ! to assign to it a strictly positive value (for example, ! an initial value). ! viscl0 is useful and represents the molecular dynamic viscosity, ! when it is constant, or a value which will be used during ! initializations (or in inlet turbulence conditions, ! depending on the user choice. ! cp0 is indispensable: it is the heat capacity, assumed constant ! in the thermodynamics available by default ! t0 is indispensable and must be in Kelvin (> 0). ! p0 is indispensable and must be in Pascal (> 0). ! With the thermodynamic law available by default, ! t0 and p0 are used for the initialization of the density. ! xyzp0 is not useful because the pressure variable directly ! represents the total pressure. ro0 = 1.17862d0 viscl0 = 4.03337d-3 cp0 = 1017.24d0 t0 = 20.d0 + 273.15d0 p0 = 1.01325d5 ! --- irovar, ivivar, icp: constant or variable density, ! viscosity/diffusivity, and specific heat ! When a specific physics module is active ! (coal, combustion, electric arcs, compressible: see usppmo) ! we MUST NOT set variables 'irovar', 'ivivar', and 'icp' here, as ! they are defined automatically. ! Nonetheless, for the compressible case, ivivar may be modified ! in the uscfx2 user subroutine. ! When no specific physics module is active, we may specify if the ! density, specific heat, and the molecular viscosity ! are constant (irovar=0, ivivar=0, icp=-1), which is the default ! or variable (irovar=1, ivivar=1, icp=0) ! For those properties we choose as variable, the corresponding law ! must be defined in usphyv !
