Water spray analysis in StarCCM+

Felipe Lopes Ribeiro · August 23, 2019, 11:37

Dear Colleagues,

I'm facing a challenge in witch I have to simulate a high pressure water spray from a descaling nozzle. In this case a continuum behavior water flow exits the descaling nozzle. After a certain distance from the nozzle, the droplets start to appear in the water spray.

I was wondering if is possible to simulate this spray focusing in its format and behavior. How can I setup this analysis? Should I use VOF with DMP model? There is a transition between the continuum water phase behavior and the dispersed phase behavior.

I found a similar analyze on this paper:

Thak you!!

In one of the latest releases VOF Blob Detection model was introduced - that should be something similar in Star.
