∇

Transport model based on the work of Sutherland [75].

Dynamic viscosity, \(\mu\) [Pa.s]

\[\mu = A_s \frac{\sqrt{T}}{1 + T_s/T}\]

Thermal conductivity, \(\kappa\) [W/mK]

\[\kappa = \mu c_v \left( 1.32 + 1.77 \frac{R}{c_v} \right)\]

Thermal diffusivity, \(\alpha_h\) [kg/ms]

\[\alpha_h = \frac{\kappa}{c_p}\]

Usage

The sutherland transport model is defined using the entries:

transport
{
    As              <scalar>;
    Ts              <scalar>;
}

Where

  • As : Model coefficient []
  • Ts : Model coefficient [K]

For example, for air:

transport
{
    As          1.4792e-06;
    Ts          116;
}
