Which is the best software for the analysis of 2 phase fluid flow?

Ansys Fluent , easy to use.

I suggest OpenFOAM and Fluent

Ansys Fluent is the best CFD software for fluid flow simulations and it is based on finite volume method formulation in which the key step is to integrate the governing equations of the fluid flow, mass or continuity equation & momentum equation, energy equation, turbulence. It provides range of two-phase flow models for modelling & simulation Eulerian-Eulerian, Mixture, Lagrangian etc. It has user-friendly graphical user interface (GUI).

Ansys Fluent is the best fluid flow analysis software.

ANSYS Fluent is known as the best Computational Fluid Dynamics software. 

In my experience, the best software is ANSYS CFX or FLUENT

Better software this kind of analysis is Star ccm+ and Ansys-Fluent

the best software is ansys workbensh fluent

ANSYS CFX is recommended software but i personally worked on ANSYS FLUENT which is also a good one.

Ansys Fluent is the most common software in this regard but Star CCM+ is developing in the world and will be top soon.

For the 2 phase fluid flow ANSYS software is best
