Показать описание
In this video tutorial transient cavitation simulation has been demonstrated. In previous video tutorial, cavitation through orifice by using mixture multiphase model has been explained.

Volume of fluid multiphase model has been selected to capture cavitation bubble formation. Bubble break-up and its formation inside nozzle has been captured by using Sharp interface option. The advancement of bubble is tracked with considering transient simulation. The k-w SST turbulent model is used in present demonstration. Total simulation has been run for 30 microsecond of flow time and animation file is created for more clarity about cavitation phenomena.

Sir excellent work, can u do absorption of ammonia by water kind of simulation using multi phase phenomenon

You should first add diesel liquid and vapor fuel properties through Fluent database.
Than only it's reflected in drop-down box of Multiphase model.

Can you please guide how to take average values of iterations we performed. And plot against those avg values

Thank you for your efforts to show this simulation. I had a question regarding the Timestep selection for transient simulations. Did you calculate using the CFL number to get the appropriate time step size? Thanks.

Sir, im not able to select diesel in multiphase model, in drop down menu, only air is available to select

In the shown animation at the end of the video, Why does the bubbles volume increase downstream whereas the pressure increases and their volume should decrease and collapse as you mentioned?

Hello sir, i want to know that can we do this method for another fluids like nitrgen and hydrogen fuels
can you please help me with this.

Is the recent iris xe graphics with the 11th gen i5 16gb ram compatible and sufficient with ansys for medium 3d simulations?
