Detailed Description

Applies sources on velocity (i.e. U) within a specified region to enable acoustic damping.

Sources applied to:

  U         | Velocity                                   [m/s]

Required fields:

  U         | Velocity                                   [m/s]

Usage

Minimal example by using constant/fvOptions:

acousticDampingSource1
{
    // Mandatory entries (unmodifiable)
    type                 acousticDampingSource;

    // Mandatory entries (runtime modifiable)
    frequency        3000;
    URef             UMean;
    origin           (-1.25 0 0);
    radius1          1.2;
    radius2          1.65;

    // Optional entries (runtime modifiable)
    w                20;

    // Conditional optional entries (runtime modifiable)
    // Either of the below

        // Option-1
        UNames           (<UName1> <UName2> ... <UNameN>);

        // Option-2
        U                U;

    // Mandatory/Optional (inherited) entries
    ...
}

where the entries mean:

Property	Description	Type	Reqd	Dflt
`type`	Type name: acousticDampingSource	word	yes	-
`frequency`	Frequency value [Hz]	scalar	yes	-
`URef`	Name of reference velocity field	word	yes	-
`origin`	Sphere centre location or damping	vector	yes	-
`radius1`	Inner radius at which to start damping	scalar	yes	-
`radius2`	Outer radius beyond which damping is applied	scalar	yes	-
`w`	Stencil width	label	no	20
`UNames`	Names of operand velocity fields	wordList	cndtnl	-
