WebFeb 21, 2024 · Bjerknes' model of the water cycle was part of his overall atmospheric circulation theory he called the "Bjerknes Circulation Theory." It detailed the global transport of heat by ocean currents, the effects of large-scale cyclones, and the movement of moisture from the oceans to the atmosphere and back. Bjerknes' model of the water … The force on a small particle in a sound wave is given by: where V is the volume of the particle, and P is the acoustic pressure gradient on the bubble. Assuming a sinusoidal travelling wave, the time-averaged pressure gradient over a single acoustic cycle is zero, meaning a solid particle (with fixed volume) experiences no net force. However, because a bubble is compressible, the oscillating pressure field also causes its volume to chang…
