So far i am working hydrodynamics of underwater vehicles using FLUENT. Now i want to do the underwater explosion analysis. Due to explosion bubbles will form with high preesure and these bubbles will exert the pressure on the nearby sturcture. Now i want to know how to simulate this bubble in FLUENT. Is anybody working on this topic. I am thankful to you for your valuable suggestions.
Re: Bubble dynamics
You can use patching to initialize the solution:
- first patch a volume of water like in any VOF simulation;
- mark a small circular region using adaption registers inside the water zone;
- patch this region with high pressure and temperature gas (this will be explosion resulted gases);
- start your unsteady simulation using an appropriate time-step.
I think that you should also pay attention to VOF specific settings that do not apply here, or apply differently!
Best wishes, Razvan
