Modeling a phenomena

Hi guys. I have a question. Do you mind if you help me right here?
We produce a new solution to regenerate membranes working in treatment water units. One individual bulb component in this solution collapse which make lots of energy and help regenerating of membrane. here is the question:
How can we model this phenomena? Is there any special tools (preferably not complicated) such as Aspen,... to predict behavior of this event?
Thanks in advance.

I suspect it might be bubble.

Modelling of bubble collapse is complex.

I would go for practial tests myself...

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
 
We use the same trick (air bumping) to remove particulates (soft sludge) in cleaning operations on shell and tube heat exchangers. Have doubts if you will find a simulation model for this.
 
If you wish to know at what conditions the bubble should collapse i think software such as HYSYS should be able to predict this (theoretically at least - if there are some local phenomena e.g. associated to rate phenomena, local variation in composition etc i dont know if this will impact the final result.)
 
I agree with LittleInch,
data measurement would be the best option,
as alternative you may create a little procedure for example in Matlab or Mathcad to model the phenomena (which probably will require to solve phase equilibria and additional constraints),
there are many software applications which, given a mixture, can export fugacities plus all other properties required (H, V etc.)
to mention a few (including free software)
Refprop
Prode Properties
Coolprop
however creating a model may require some time and you should verify accuracy.
