Turbulent intensity kinetic energy

Table of Contents

• Properties
• Usage
• Further information

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 zero gradient 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;
}
