Bases: BaseARF, BaseSphereFrequencyComposite, BaseSolution

ARF class for Gor’kov (1962)

The standing wave solution is based on equation (13) of the paper and the traveling wave solution on equation (10).

Note

This model is based on the following assumptions:

\(\lambda\gg R\)
Inviscid fluid
Compressible (fluid-like) sphere

Parameters

f (Frequency | float | int) – Frequency [Hz]
R_0 (Sphere | float | int) – Radius of the sphere [m]
rho_s (float) – Density of the fluid-like sphere [kg/m^3]
c_s (float) – Speed of sound of the fluid-like sphere [m/s]
rho_f (float) – Density of the fluid [kg/m^3]
c_f (float) – Speed of sound of the fluid [m/s]
p_0 (float) – Pressure amplitude of the field [Pa]
wave_type (WaveType) – Type of incident wave (traveling/standing)
position (None | float, optional) – Position in the standing wave field [rad]
Default: None
