Method Details

[hide private]

set_shear_value(self, value)

source code

Set the shear value for the wind profile. The default is 0.2, will depend of the site roughness

get_velocity_at(self, pt_array)

source code

Return the velocity for a point in the absolute referential. The wind tower model is applied.

Parameters:

pt_array (a Numpy array) - a position vector of shape 3x1
In the referential used, pt_array[2] will be the height along the z axis.

Returns: a Numpy array

the wind vector of size 3x1

_enable_dynamic_wake(self, enable)

source code

If True, enable the dynamic wake on each aerodynamic section. A private method, the user needs to use enable_dynamic_wake.

run_unsteady_for(self, time_length, nb_pts=100)

source code

Run the unsteady Blade Element Momentum code for the time_lenght. nb_pts is an integer that gives the number of calculation points for one revolution. This method is used only when there is no coupling with MBDyn, this is else the MBDyn solver that gives the current time.

run_unsteady_at_time(self, time)

source code

Run the unsteady BEM code calculations on the whole turbine at a given time. At the end, nothing is saved
