hi all iam simulating oil n water mixture..in a horizontal pipe..the flow is turbulent..i want to find the fluid flow characteristics of dispersed flow... which model is suitable for this kind of application...can any one suggest me...can i use VOF model????

any suggestions is highly appreciated

thanks in advance Rashmi

Eulerian. I've done it before. Use very very low URFs (say around 0.2 for most quantities). Also perform only transient simulations.

so can eularian model can simulate the turbulent flows...

can u send me the report we u have done any work using eularian... i will be very much thank ful to u if u could do that.. thanks Rashmi

What is it that you exactly need; what kind of "report" are you referring to?

hi

you said u have used eularian model b4...so is their any report u have made of ur work..

No, I have made no reports on the usage of the Eulerian model. However, if you will take the time to explain the problem you are facing, I might be able to help.

Your earlier statement "...so can eularian model can simulate the turbulent flows..." suggests that you have some confusion in understanding that the eulerian model is a multiphase model in contrast to other models such as the k-e model which are turbulence models. The Eulerian model by itself does not account for turbulence. Activating the k-e model includes a turbulent stress term in the governing equations of the eulerian model which simulates turbulence. In summary, the Eulerian model can be used in conjunction with the k-e turbulence model to account for turbulence in multiphase flows.

Hi i suggested to do VOF model because it is only used for two fluid and u said that u mixing the two fluid in a pipe then VOF is best model for that i doing VOF model for slidin g a sheet in a fluid and using VOF model.any problem then send whole detailed on ms_project05@rediffmail.com
