QuickGauss3D {wflo}

For an incoming wind speed at reference height, this function computes a 3D Gaussian model based wind speed.

Description

This function computes Gaussian wind speeds.

Usage

QuickGauss3D(x, y, z, u = 8, refHeight = 10)

Arguments

x

must be a single value. Provide distance in meters.

y

must be a single value. Provide distance in meters.

z

must be a single value. Provide distance in meters.

u

must be a single value. Provide wind speed in meters per second.

refHeight

must be a single value. Provide reference height (the height at which wind speed u was measured) in meters.

Details

The Gaussian wake model is loosely based on the initial contribution by Bastankhah & Porte-Agel (2014).

Value

QuickGauss3D returns a single number which can be considered a wind speed in the wake of a turbine at location x, y, and z.

Note

Note that the model assumes that along the x axis, x = 0 is the turbine location. x expands along the wind direction downwind. y denoted whether a point is 'left' or 'right' the x axis. Thus, the x-z plane is the plane along the x axis and perpendicular to the ground. The z axis is hight, starting at 0 = ground level.
