Notizen:
A periodic pulsation of the frothing mass of liquid and vapor on a sieve tray and a bubblecap tray is reported. An equation is proposed which relates the frequency of the oscillation to the velocity of sound, the physical dimensions of the systems, and the flow rates of the gas and liquid. The equation is a modification of the acoustical analogy to the classical Helmholtz resonance in electrical circuits having both capacitance and inductance. The oscillation is shown to decrease back-mixing on the tray, and thus to result in an increase in the Murphree vapor efficiency.
