Default method to determine jet front
Posts: n/a
Hi All, I am simulating one liquid injecting into another liquid in a tank and trying to determine the transient jet front and shape. I noticed there are different jet length when I use different values of volume fraction in the jet contour plot. Same thing happens while using different jet velocities for determining the jet boundary. This led me to think about the criteria for determining the jet shape in previous jet experiments. How to match the test data with CFD?
