UDF for solidification

ZiadElSayed · June 25, 2020, 11:58

Hello everyone,

I am trying to model a solidification process for composite material consisting of molten aluminium and specific volume of NaCl particles.

My model is composed of two stages:

1- Flow using Euler-Granular multiphase flow.
2- Solidification of the composite

Unfortunately, its not possible to use solidification module in Ansys when using Euler multiphase flow, I have been trying to work around that.

The objective is the study is to simulate the contraction and heat transfer between the particles of the NaCl and the molten Aluminium. I am not really sure if that's possible or not.

I would like to know your opinions, I have previously been told its possible to make a UDF for solidification in case of Euler model, I have never worked with UDF so I am not really sure how to start.

Also, are there any other alternatives possible for my case?

Thanks in advance.

Does anyone have any idea how to help me with that?

sounds like film formation simulation.
But I have no experience
