Class
    Foam::KinematicWeberNumber
 
Group
    grpLagrangianIntermediateFunctionObjects
 
Description
    Calculates and writes particle Weber number field on the cloud.
 
    \f[
        \mathrm{We}_p =
            \frac{\rho_c \, | \mathbf{u}_\mathrm{rel} |^2 \, d_p }{\sigma}
    \f]
 
    \vartable
        \mathrm{We}_p  | Particle Weber number
        \rho_c         | Density of carrier
        d_p            | Particle diameter
        \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>/We

Usage
    Minimal example by using \c constant/<CloudProperties>:
    \verbatim
    cloudFunctions
    {
        KinematicWeberNumber1
        {
            // Mandatory entries
            type             WeberNumber;
            sigma            <scalar>;
        }
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property     | Description                 | Type   | Reqd | Deflt
      type         | Type name: WeberNumber      | word   | yes  | -
      sigma        | Surface tension [N/m]       | scalar | yes  | -
    \endtable
