Why are the particles concentrated in the nodal planes for only a period of time?

As you can see from the attached diagram, the particles are concentrated in the nodal planes at 0.008 s. But at 0.1s, the particles are not as concentrated in the nodal planes as at 0.008 s ( i.e....

Look into my acoustic pressure field, does it look like having an acoustic streaming?

Why is it that in the middle there are no standing wave field?How will the particles move when the standing wave field is only on the upper and lower of the cavity?

What can you deduce from my 1D plot graph of the mass fraction of suspended particles in a standing wave field?

The y-axis shows the mass fraction of the suspended particles and the x-axis shows the length of the cavity. When x = 0, that is to the left end wall of the cavity, when x = 21, that is at the...
