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

AI Thread Summary
To simulate particle movement influenced by ultrasonic waves, understanding the acoustic radiation force is essential, as it directly affects particle dynamics. Calculating movement solely based on the velocity field is inadequate because it does not account for the forces acting on the particles. The discussion raises questions about the applicability of this model across different frequency ranges, particularly whether it is limited to audible frequencies. Additional context about the specific simulation goals is necessary for more targeted assistance. Providing detailed information will enable more effective guidance from the forum members.

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

Thread 'Entropy and configurations of microstates'

I was watching a Khan Academy video on entropy called: Reconciling thermodynamic and state definitions of entropy. So in the video it says: Let's say I have a container. And in that container, I have gas particles and they're bouncing around like gas particles tend to do, creating some pressure on the container of a certain volume. And let's say I have n particles. Now, each of these particles could be in x different states. Now, if each of them can be in x different states, how many total...

Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'

Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...

Thread 'Condensate rate of water for an air conditioning cooling coil'

I need to calculate the amount of water condensed from a DX cooling coil per hour given the size of the expansion coil (the total condensing surface area), the incoming air temperature, the amount of air flow from the fan, the BTU capacity of the compressor and the incoming air humidity. There are lots of condenser calculators around but they all need the air flow and incoming and outgoing humidity and then give a total volume of condensed water but I need more than that. The size of the...
