acdecom.WaveGuide.K0_dokumaci

WaveGuide.K0_dokumaci(m, n, f, **kwargs)

Dissipation function for the wavenumber based on Dokumaci’s thermo-viscous dissipation in waveguides with flow and higher-order modes.

Parameters

• m (int or array_like) – Mode-order in the first direction. If the waveguide is circular, m indicates the circumferential mode-order. The plane wave has the order 0.

• n (int or array_like) – Mode-order in the second direction. If the waveguide is circular, n indicates the radial mode-order. The plane wave has the order 0.

• f (float, optional) – Frequency in Hz.

• kwargs (additional arguments) –

Returns

The dissipation factor of the (m,n)-mode at the frequency f [Hz].

Return type
