OyeDynamicWake

The Oye dynamic wake model captures the lag in induction in response to a change of inflow conditions. It is the most accurate model for linearisation and time domain, but it does increase linearisation time significantly as it introduces extra states.

  • DynamicWakeType: string = OyeDynamicWake
  • AreaAveragingMethod: string = OVER_ANNULUS | NONE
  • DynamicTangentialInduction: boolean
  • OyeTimeLagMultiplier: number

A type of DynamicWake

Properties

AreaAveragingMethod: string, optional

With the "over annulus" method, the dynamic wake is calculated over the entire annular ring. Induced velocities are averaged over the number of blades. If "none" is selected, the annulus is divided into segments to which separate dynamic wakes are applied.

default = OVER_ANNULUS

DynamicWakeType: string

Defines the specific type of DynamicWake model in use. For a OyeDynamicWake object, this must always be set to a value of OyeDynamicWake.

DynamicTangentialInduction: boolean, optional

If false, the tangential induction will be solved by iteration on each time step, as per the Pitt and Peters model.

default = True

OyeTimeLagMultiplier: number, optional

The time constant for the Oye dynamic wake model.

default = 1.0
