Karman vortex street formula
In fluid dynamics, a Kármán vortex street is a repeating pattern of swirling vortices caused by the unsteady separation of flow of a fluid around blunt
A triangle wave is a non-sinusoidal waveform named for its triangular shape. It is a periodic, piecewise linear, continuous real function.
Photoacoustic Doppler effect
The photoacoustic Doppler effect is one specific kind of Doppler effect, which occurs when an intensity modulated light wave induces a photoacoustic wave
The Weber number (We) is a dimensionless number in fluid mechanics that is often useful in analysing fluid flows where there is an interface between two
Wavelength of sound waves
In the case of longitudinal harmonic sound waves, the wavelength can be calculated by the distance the point has traveled from the wave’s source, the
Ripple factor (choke)
For the root mean square value of the ripple voltage, the calculation is more involved as the shape of the ripple waveform has a bearing on the result.
