Default how to simulate splash process
Posts: n/a
My model is a cylinder container, water and air two phase, with a rushton impeller a few centimeters below the water-air interface. I used sliding mesh and VOF simulation to track air-water interface movement. I got pretty good results. However, in reality, I have seen splashing process, water droplets are formed at certain rotational speed and transported to the top lid of the container. But the Fluent simulation does not show this splashing process even at very high rotational speed. Could anyone share your experience for simulating splashing of water droplts into air (initial, water-air interface is flat). Thank you.
