modelling a vibrating circle

Hi Part of my project is to attempt to model a pulsating circle.
I'd like to see it create variations in the pressure of the fluid, the output would look like the ripples in a pond when a stone has been thrown in. Have no idea where to start so any information, no matter how basic would be much appreciated. I am new to the product so keep answers as simply put as possible please. Thanks |

What kind of oscillations the circle performs.There are many analytical solutions available for radially oscillating problems.Check any book on acoustics.

A simple sinusoidally varying oscillation will do, any books in particular that you'd recomend, preferable directly compatible with FLUENT?
Also i have been told that the problem involves dynamic meshes, are there any help guides that you would advise? |

Acoustics book by Morse and Ingard is a classical book and you can find many similar problems in there.As a first step I would not advice using a dynamic mesh since your oscillations are just sinusoidal.Look in the literature.The sinusoidal oscillations can be used as a boundary condition for solving the problem rather than using dynamic meshes.

I suggest you try using matlab for solving this problem. If the governign equations are simple, u can easily code them. lots of visualization tools too.
