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?

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....

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...

For the COMSOL simulation of particle manipulation using ultrasonic standing wave, why is the resonant freq. different at different mesh sizes?

I have attached two diagrams, one is for an extra-fine mesh and the other is for an extremely fine mesh. I am using PZT-4D and my suspended particles are polystyrene particles in water.  The...

Why are my 1D and 2D plot results look different [COMSOL, ultrasonic standing wave on suspended particles]?

As you can see from at 0.013 and 0.02s,the 2D plot graph does not show any changes but from the 1D plot graph, it shows changes. Why is that so?  Both plot shows the changes to the mass fraction...
