Sutherland

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;
}
