How Reacting Multiphase flow model available with OPENFOAM is different from eulerian model of ANSYS Fluent? What are the governing equations and where can we find the closure schemes of various turbulence models of OPENFOAM?
In reacting multiphase flow modeling, the governing equations further include chemical reactions governed by species balance equations. Based on the mass, energy conservation and pre-defined chemical reactions’ kinetics, the species balance equations solve for void fraction, density of each phase, as well as mass fractions of all species within each phase.

Openfoam works in numeric background. Which yields good optimized results by obeying three approach
- Eulerian – Lagrangian Approach : Utilises Eulerian framework for the continuous phase and Lagrangian framework for dispersed phases
- Eulerian – Eulerian Approach : Utilises Eulerian framework for both the phases
- Volume of Fluid Approach : Eulerian framework for both the phases with specialised interface treatment.
