How Does Acoustic Radiation Force Affect Particle Movement in Ultrasonic Waves?

[wt1987]

Hello everyone,

I want to calculate or rather simulate a particle movement by influence of a ultrasonic wave.
I have read many times that I have to use the acoustic radiation force for calculating the movement of a particle but not why?

At first I calculated the particle movement only with the velocity field and it doesn`t work but why?
Is this only possible in the audible range of acoustic frequencies?

Can you help me?

Best regards
