Class
    Foam::ThermoReynoldsNumber
 
Group
    grpLagrangianIntermediateFunctionObjects
 
Description
    Calculates and writes particle Reynolds number field on the cloud.
    The normalisation factors are calculated with thermal effects.
 
    \f[
        \mathrm{Re}_p =
            \frac{\rho_c \, | \mathbf{u}_\mathrm{rel} | \, d_p}{\mu_c}
    \f]
 
    \vartable
        \mathrm{Re}_p  | Particle Reynolds number
        d_p            | Particle diameter
        \rho_c         | Density of carrier in the film surrounding particle
        \mu_c    | Dynamic viscosity of carrier in the film surrounding particle
        \mathbf{u}_\mathrm{rel} | Relative velocity between particle and carrier
    \endvartable
 
    Operands:
    \table
      Operand        | Type         | Location
      input          | -            | -
      output file    | -            | -
      output field   | scalarField  | <time>/lagrangian/<cloud>/Re
    \endtable
 
Usage
    Minimal example by using \c constant/<CloudProperties>:
    \verbatim
    cloudFunctions
    {
        ThermoReynoldsNumber1
        {
            // Mandatory entries
            type             ReynoldsNumber;
        }
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property     | Description                | Type   | Reqd | Deflt
      type         | Type name: ReynoldsNumber  | word   | yes  | -
    \endtable
 
Note
  - Normalisation factors \c rhoc and \c muc are based on temperature
    dependent values calculated inside the film surrounding the particle
    rather than freestream values; therefore, the thermo \c ReynoldsNumber
    should not be expected to operate with kinematic (non-thermo) applications.
