Lagrangian-Eulerian (LE) approach for multiphase flows. The LE approach is based on a statistical description of the dispersed phase in terms of a stochastic point pro-cess that is coupled with an Eulerian statistical representation of the carrier fluid phase.

Answer - The short answer is: the mathematical description. To be clear, Ansys Fluent has three multiphase models that are based on an Eulerian framework, also called an Euler-Euler approach: Volume of Fluid (VOF), Mixture, and Eulerian models. In this context, the term "Eulerian" is used for the mathematical description used, but also for

A multiscale model for dilute turbulent gas-particle flows based on the equilibration of energy concept. The objective of this study is to improve Eulerian-Eulerian models of particle-laden turbulent flow.

The main CFD approaches to multiphase flow modeling are Euler-Euler (E-E) and Euler-Lagrange (E-L). In the E-E framework, both continuous and dispersed phases are viewed as continua that can interact with each other. Averaging methods based on volume, time, or ensemble averages are used to formulate the governing equations.

16.5.1 Overview and Limitations of the Eulerian Model. Overview. The Eulerian multiphase model in ANSYS FLUENT allows for the modeling of multiple separate, yet interacting phases. The phases can be liquids, gases, or solids in nearly any combination. An Eulerian treatment is used for each phase, in contrast to the Eulerian-Lagrangian treatment
