Modelling Cavitation Using Vorticity

Modelling Cavitation Using Vorticity

Watching high speed photographs of the formation and implosion of bubbles during cavitation process in water, it can be seen that they are always associated with vortices. We claim that they appear and disappear as a subproduct of a very strong vorticial phenomena. To show it we are first going to e...

Zusammenfassung:Watching high speed photographs of the formation and implosion of bubbles during cavitation process in water, it can be seen that they are always associated with vortices. We claim that they appear and disappear as a subproduct of a very strong vorticial phenomena. To show it we are first going to express Navier Stokes equations in terms of vorticity giving rise to the vortes transport equation.
