TurbVelocityFieldBts

class sharpy.generators.turbvelocityfieldbts.TurbVelocityFieldBts

Turbulent Velocity Field Generator from TurbSim bts files

TurbVelocitityFieldBts is a class inherited from BaseGenerator

The TurbVelocitityFieldBts class generates a velocity field based on the input from a bts file generated by TurbSim. https://nwtc.nrel.gov/TurbSim

To call this generator, the generator_id = TurbVelocityField shall be used. This is parsed as the value for the velocity_field_generator key in the desired aerodynamic solver’s settings.

The settings that this solver accepts are given by a dictionary, with the following key-value pairs:

Name	Type	Description	Default
print_info	bool	Output solver-specific information in runtime	True
turbulent_field	str	BTS file path of the velocity file	None
new_orientation	str	New orientation of the axes	xyz
u_fed	list(float)	Velocity at which the turbulence field is fed into the solid	numpy.zeros
u_out	list(float)	Velocity to set for points outside the interpolating box	numpy.zeros
case_with_tower	bool	Does the SHARPy case will include the tower in the simulation?	False
interpolate_wake	bool	If False, u_out will be assigned to all the points in the wake	True
num_cores	int	Number of cores to be used in parallel computation	1
extra_offset	float	Distance [m] to displace the turbulence box	0.0
use_3_4_interpolation	bool	Use the farfield velocity at 3/4 chord for all the points along the chord	False
