Description

This boundary condition provides a volumetric- OR mass-flow normal vector boundary condition by its magnitude as an integral over its area with a swirl component determined by the angular speed, given in revolutions per minute (RPM)

The basis of the patch (volumetric or mass) is determined by the dimensions of the flux, phi. The current density is used to correct the velocity when applying the mass basis.

Usage

    Property     | Description             | Required    | Default value
    phi          | flux field name         | no          | phi
    rho          | density field name      | no          | rho
    flowRate     | flow rate profile       | yes         |
    rpm          | rotational speed profile | yes        |

Example of the boundary condition specification:

<patchName>
{
        type            swirlFlowRateInletVelocity;
        flowRate        constant 0.2;
        rpm             constant 100;
}

Note

• the \c flowRate and \c rpm entries are Function1 types, able to describe time varying functions. The example above gives the usage for supplying constant values.
• the value is positive into the domain
