2 phase flow cfdThe grid generation issues found in the 3D simulation of two-phase flow in a pipe using Computational Fluid Dynamics CFD are discussed in.In this paper the CFX Ansys Code was employed for simulation of two-phase flow in pipe bends subjected to erosion due to liquid or solid particles. The.In fluid mechanics, two-phase flow is a flow of gas and liquid — a particular example of multiphase flow. Two-phase flow can occur in various forms, such as flows transitioning from pure liquid to vapor as a result of external heating, separated flows, and dispersed two-phase flows where one phase is present in the form of particles, droplets, or bubbles in a continuous carrier phase i.e. Booth trade show grab. So, to get ure real solution, Fluent must lower ure water height from 3 cm to 2 cm right???The water will loose height due to friction with the air phase, or the air phase is 1000 times lighter than the water, so lowering water height to 2 cm will recomend an enormous amount of momentum transfer..... I think that u will need a lot more of pipe length to get a fully developped flow.SO the best solution in my opinion is to have a single inlet, with water and air coming from it.

This is the best choice, unless u are searching to calculate the length needed by the flow to fully developp....2- 50 m is enormous....u will need a lot of time to converge(if u want to do a DNS with grid independance solution, u will need more than a year of calculation..)..length needed by the flow to be fully developped depends on the volume fraction, on the fluid proprieties, the flow configuration and the pipe diameter....Some flows as slug flows sometimes need 100 m to get a fully developped state..the length needed depnds on every simulation... If ure pipe diameter is d, i think a length of 100 d is really sufficiant. If ure simulation shows that 100 d was not enough, than u can try a longer pipe....If u give me more details about ure pipe diameter and the flowrates that u want to simulate, i can maybe advice u more .Hope that i could be clear If u need anything more, tell me please and tell me about ure results whenever u get it.

If i define one of this solution as a dispersed fluid i have to define the mean diameter, what would be the mean diameter for a liquid that have almost the same density as water? Before you jump into questions about multiphase flow - is this flow actually a multiphase flow? * Multicomponent mixture - this is a little more complex.A multiphase flow model is not much use if it is not a multiphase flow. Is it something dissolved in a liquid (for instance salt in water)? It can do everything the additional variable approach can do but it can also model the change of physical properties on the liquid. do you mean that i have to define the salted water as a multicomponent mixture (Water and Salt) and define its properties in CFX Pre? A dissolved substance in a liquid can be modelled two ways: * Additional variable - this is very simple, easy and does not add much to the complexity of the model.
