Multiphase

This analysis type is used to simulate the time-dependent behavior of fluid mixtures, for example air and water. The analysis is carried out using the VoF (Volume of Fluid) method which is a standard approach for the computation of multiphase systems. | Page 21

Quick assessment of the water level of a cooling tower water distribution open channel.
Multiphase flow. constant density, no energy equation.
The channel has a water inlet and numerous holes for outlet, while it is open to the atmosphere.

The fluid flow through various systems in different fields follows a vivid pattern pertaining to the various phases that it may contain. One of the examples could be two phase flow in which two phases, i.e. gas and liquid, exist simultaneously. This type of flow can be seen in oil and gas industries

 where the performance of the system depends upon the flow regimes in which it operates. Few flow regimes, such as the churn flow is undesirable in few cases. Our aim is to replicate this flow and study its behaviour using an experimental setup.

First attempt to study the flow of a 5-meter length boat at her critic Froude number

Predict the resistance (the total and later split this in their components) in calm water using a multiphase solver to compute the elevation of the free surface too. Incompressible, isothermal and viscous flow, with the use of wall functions and a turbulance model.
