Defining porosity using Power law

  • Porosity could be also modeled by the so called Power law
  • For each cellZone the following is defined in the file system/fvOptions :
            type powerLaw;

        powerLawCoeffs
        {
              C0 0.5;
              C1 2.0;
        }
  • The source term is
    183(17.8)

     

    so the resistance is – in contrast to the Darcy law – isotropic, not directional.
