SlotJet¶
- class acoular.environments.SlotJet¶
Bases:
FlowField
Provides an analytical approximation of the flow field of a slot jet, see Albertson et al., 1950.
- v0 = Float(0.0, …¶
Exit velocity at jet origin, i.e. the nozzle. Defaults to 0.
- origin = CArray( dtype=float64, shape=(3, ), value=array((0., 0., 0.)), …¶
Location of a point at the slot center line, defaults to the co-ordinate origin.
- flow = CArray( dtype=float64, shape=(3, ), value=array((1., 0., 0.)), …¶
Unit flow direction of the slot jet, defaults to (1,0,0).
- plane = CArray( dtype=float64, shape=(3, ), value=array((0., 1., 0.)), …¶
Unit vector parallel to slot center plane, defaults to (0,1,0).
- B = Float(0.2, …¶
Width of the slot, defaults to 0.2 .
- v(xx)¶
Provides the flow field as a function of the location. This is implemented here only for the component in the direction of
flow
; entrainment components are set to zero.- 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.
