Properties
ReferenceHeight: number (m), optionalcoming soon
The reference height for the wind field, above which the free-field wind conditions take over. If this is omitted, the hub height will be used, and if there is more than one the highest hub height.
Inclination: number (rad), optionalcoming soon
The inclination of the flow relative to the horizontal plane. Typically this is in the order of 8 degrees for an onshore turbine, and 0 degrees for an offshore turbine.
default = 0.0
UseGustPropagation: boolean, optionalcoming soon
If true, gust propagation will be applied (where the transient properties only "arrive" at the turbine as the flow does). This is only relevant to transient flows.
Direction: number (rad), optionalcoming soon
The (constant) direction of the wind relative to the global X axis.
DirectionVariation: object (a type of WindDirectionVariation), optional coming soon
A defined variation in the wind direction.
Can be any of the following types:
SteadyWakeDeficit: object (a type of SteadyWakeDeficit), optional coming soon
A simple model for the reduced velocity of the wind behind another turbine. This deficit will be applied across a certain region, and this region will not move around during the simulation.
Can be any of the following types:
VerticalShear: object (a type of VerticalShear), optional coming soon
The vertical wind shear, modelling the reduction in the wind velocity as you get closer to the ground. The reference height delimits the height above which the free-field wind conditions resume.
Can be any of the following types:
VerticalDirectionShear: number (rad/m), optionalcoming soon
The vertical direction shear, otherwise known as "wind veer". This models the case where the direction of the wind field varies as the height increases.
DynamicUpstreamWake: object(DynamicUpstreamWake), optionalcoming soon
The representation of an upwind turbine's wake impinging on the simulated turbine. This can include meandering wake, where the velocity deficit moves around relative to the simulated turbine.
WindType: stringcoming soon
Defines the specific type of Wind model in use. For a LaminarFlow object, this must always be set to a value of LaminarFlow.
MeanSpeed: number (m/s), optionalcoming soon
The (constant) mean wind speed for the duration of the simulation.
MeanSpeedVariation: object (a type of WindMeanSpeedVariation), optional coming soon
A defined variation in the mean wind speed.
Can be any of the following types:
VerticalShearVariation: object (a type of WindVerticalShearVariation), optional coming soon
A defined variation in the vertical wind shear.
Can be any of the following types:
HorizontalShearVariation: object (a type of WindHorizontalShearVariation), optional coming soon
A defined variation in the horizontal wind shear.
Can be any of the following types:
DirectionShearVariation: object (a type of WindDirectionShearVariation), optional coming soon
A defined variation in the direction wind shear.
Can be any of the following types:
