Detailed Description

Applies sources on velocity field (i.e. U) within a specified region to enable actuator disk models with radial thrust distribution for aero/hydro thrust loading of horizontal axis turbines on surrounding flow field in terms of energy conversion processes.

Sources applied to:

  U         | Velocity    [m/s]

Required fields:

  U         | Velocity    [m/s]

Thrust, which is computed by actuationDiskSource.H is distributed as a function of actuator disk radius through a given forth order polynomial function:

\[ T(r) = T (C_0 + C_1 r^2 + C_2 r^4) \]

where

\( T \)	=	Thrust magnitude computed by actuationDiskSource setup
\( T(r) \)	=	Thrust magnitude as a function of "r"
\( r \)	=	Local actuator disk radius
\( C_* \)	=	Polynomial coefficients

Usage

Minimal example by using constant/fvOptions:

radialActuationDiskSource1
{
    // Mandatory entries (unmodifiable)
    type            radialActuationDiskSource;

    // Mandatory entries (runtime modifiable)
    coeffs          (0.1 0.5 0.01);

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

where the entries mean:

Property	Description	Type	Reqd	Dflt
`type`	Type name: radialActuationDiskSource	word	yes	-
`coeffs`	Radial distribution function coefficients	vector	yes	-

The inherited entries are elaborated in:

Note

radialActuationDiskSource computes only Froude force computation method of actuationDiskSource.
