How to capture numerous discrete, micro-scale, and high-temperature VOF liquid lumps
I am going to capture and quantify the generated micro-scale and high-temperature droplets (or particles) during the laser cutting process using Fluent. Two approaches have been applied but with problems as follow:
1. VOF-to-DPM is applied successfully to capture and transfer small liquid lumps into DPM particles. However, the DPM particles will consistently keep the high temperature in the following flow process shown as in the figure below. The fact should be that the DPM particles will continue to be cooled down by surrounding air.
2. Only VOF is activated for the multiphase simulation of the laser cutting process. But when it comes to post-processing, we found it is very hard to capture so many separate liquid lumps not even to analyze the mass and velocity of the lumps.
I am wondering if there is any code that could enable us to capture separate VOF liquid lumps (like VOF-to-DPM technique) during post-processing or if there is any way to activate the heat transfer of DPM particles?
