The expression of multiphase fluid flow might be indicated as "number of phases" + "flow" in accordance with the total number of phases. For instance, the mixture of liquid water and liquid oil can be classed as a two-phase flow or a multiphase flow. On the upshot, multiphase flow is the interaction of more than one matter or phase of

the theoretical foundation, modeling issues, and numerical implementation of the 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.

The coupled model has been developed as a new multiphase flow model, the Eulerian multi-fluid VOF model, in the ANSYS Fluent software. The coupled model is designed to simulate the computational domain containing the area wherein the fluids are separated, which is evaluated using the VOF model, and the area wherein the fluids are mixed, which

The single-phase slurry approach is not sufficient to describe the effects of particle size and concentration of the solid phase on pump performance; for this reason, this paper examines a multi-phase CFD model applied to a dredge pump. The solid phase is modelled with an Eulerian approach, in order to reduce the computational effort required

In the Eulerian approach (also known as Euler-Euler or multi-phase model), two or more phases of gas, fluid, or solid are treated as continuous phases. This means that all phases coexist everywhere in the domain while each phase's volumetric fraction is considered a continuous parameter in space and time.

I am using ANSYS FLUENT to model a two-phase flow of liquid and gas where the surface tension force is included. In the theory of the VOF model, the surface tension force is added to the momentum equation as a source term.

Debris flows are catastrophic landslides owing to their very high velocities and impact. The number of such flows is likely to increase due to an increase of extreme weather events in a changing climate. At the same time, risk reduction and mitigation plans call for a quantitative assessment of the hazard. Numerical models are powerful tools in quantifying debris flows in terms of flow height
