Turbulent intensity kinetic energy

Properties

• based on the inlet-outlet condition
• sets the turbulent kinetic energy based on the patch velocity and user-supplied turbulence intensity

$$k_p = 1.5 \left( I \mag{\u} \right)^2$$

• in the event of reverse flow, a zeroGradient condition is applied, i.e.

$$\frac{d k}{d x} = 0$$

Usage

The condition is specified in the field file using:

<patchName>
{
    type        turbulentIntensityKineticEnergyInlet;
    intensity   0.05;
    value       <field value>;

    // Optional entries
    U           U;
    phi         phi;
}
