RotatingFlow¶
- class acoular.environments.RotatingFlow¶
Bases:
FlowField
Provides an analytical approximation of the flow field of a rotating fluid with constant flow.
- rpm = Float(0.0, desc='revolutions per minute of the virtual array; negative values for clockwise rotation')¶
Exit velocity at jet origin, i.e. the nozzle. Defaults to 0.
- origin = CArray(dtype=float64, shape=(3,), value=array((0.0, 0.0, 0.0)), desc='center of nozzle')¶
Location of the nozzle center, defaults to the co-ordinate origin.
- v(xx)¶
Provides the rotating flow field around the z-Axis as a function of the location.
- Parameters:
- xxarray of floats of shape (3, )
Location in the fluid for which to provide the data.
- Returns:
- tuple with two elements
The first element in the tuple is the velocity vector and the second is the Jacobian of the velocity vector field, both at the given location.
