Introduction to the ANSYS Fluent Hybrid VOF to DPM Model
This webinar will discuss ANSYS Fluent’s Hybrid VOF to DPM multiphase model, which allows users to model primary atomization and subsequent breakup, evaporation and chemical reactions in the same setting.

The Volume of Fluid (VOF) model tracks the liquid-gas interface while the Discrete Phase Model (DPM) is a separate model that tracks discrete droplets suspended in an Eularian phase.

The heart of the VOF to DPM model is an algorithm that identifies liquid spheroids that get separated from the main liquid body of the spray and then converts them into point masses for further tracking. This method eliminates the need to track the interface of smaller drops and thus reduces the need to have very fine meshes.
A second important piece of this hybrid model is dynamic mesh refinement and coarsening, which automatically adjusts the local mesh density as needed. These advances make the simulation of spray processes with the finest details much more computationally efficient.
