One-way coupling simulation of the pressure-swirl atomizer

HengLiu · May 26, 2022, 11:41

Good day, everyone!

I obtained the file "vof_spray.dat" from a VOF simulation of the pressure-swirl atomizer. Near the orifice, the cell size is about 0.01875mm.

After running the One-way coupling simulation with CONVERGE v3.0.23, the spray shape seems incorrect even though it's a hollow cone spray. As shown in the attached file, the parcels are injected in clusters. I utilized the LISA model and actived the collision model for parcles. There was no improvement even I embedded the cell size near the nozzle or increased the number of parcels in One-way simluation.

Could somebody give me some advice on the One-way coupling simluation of the pressure-swirl atomizer?

Thanks.

Hi HengLiu, thank you for your question.

Could you mail the support team at CONVERGE with your case setup at support@convergecfd.com? This looks like it needs more context to be answered right.
