# ShearVelocityField¶

class sharpy.generators.shearvelocityfield.ShearVelocityField[source]

Shear Velocity Field Generator

ShearVelocityField class inherited from BaseGenerator

The object creates a steady velocity field with shear

$\hat{u} = \hat{u}\_\infty \left( \frac{h - h\_\mathrm{corr}}{h\_\mathrm{ref}} \right)^{\mathrm{shear}\_\mathrm{exp}}$
$h = \zeta \cdot \mathrm{shear}\_\mathrm{direction}$

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

Name

Type

Description

Default

u_inf

float

Free stream velocity magnitude

None

u_inf_direction

list(float)

x, y and z relative components of the free stream velocity

numpy.array

shear_direction

list(float)

x, y and z relative components of the direction along which shear applies

numpy.array

shear_exp

float

Exponent of the shear law

0.0

h_ref

float

Reference height at which u_inf is defined

1.0

h_corr

float

Height to correct shear law

0.0
