Dynamic Meshes with Mixture Model
Hello
Has anyone successfully worked with a mixture multiphase model with dynamic meshes option !? Looks Like Fluent has some difficulty in computing Mixture Models with Dynamic Grids ! Any comments is well appreciated. Thanks CFDtoy |
Re: Dynamic Meshes with Mixture Model
Hi,
It's no problem even VOF model. Mixture Model is not complex model in Fluent multiphase models. If it is Euler-Euler or Euler-Granular, it will be very tough calculation without MDM. Thank you FJ |
Re: Dynamic Meshes with Mixture Model
Hi
FLuent is not compatible with VOF Model and Dynamic Grids ! Only Mixture and Discrete Models are..but looks like Fluent simulations have some intricate problems when predicting cavitation and other other phenomena associate d with multiphase flows. thanks CFDtoy |
Re: Dynamic Meshes with Mixture Model
Hi,
Yes, you are right. They said "Fluent is not compatible with VOF Model and Dynamic Grids". But I don't think so from those equations. So I checked and the results were O.K. All phases mass and volume became conservation and it good agree with the experimental results. From those equations of Dynamic Grids, I understand that both VOF and Mixture model is no problem because their scalars transport based on the mixture velocity. For Euler-Euler model ,I said it's O.K but I reconsider the equations again , It's maybe impossible. Thank you FJ |
