Literature on Solidification/Melting
 
Hi all,
I am looking for literature on Solidification/Melting process involving gas phase as well. For example, a container filled with half liquid and 1/2 gas on top cooled and solidified. such a system representing 3 phase in reality - liquid-solid-gas. I found a lot of literature for pure melting or solidification with liquid-solid alone but not with additional gas component.

Kindly suggest me some literature/experiments which I can use for model validation.

Thanks,

CFDtoy

Re: Literature on Solidification/Melting
 
I am also looking for three-phase models for melting/solidifcation with gas. My application is like this: a laser is scanning a powder bed. It is part of laser cladding with pre-placed powder. I think it is difficult to track every single powder particle. So it is better to use a mixture continuum model. My first question is under what conditions (when) the gas between particles escape out from molten powder material. Does anyone know literature dealing with this kind of problem? Thanks!

Literature on Experimental data
 
Hi James,
You can use commercial CFDwares to run 3 phase ..some of them already have 3 phase models. I am looking for experimental values to validate my modeling part. Fluent uses contiuum approach..i am doing multi-fluid approach, treating liquid,gas, solid separate and using interaction terms in the segregated momentum eqns to solve the flow problem with phase change.

Kindly let me know if you have some experimental literature data for this.

Thanks.

CFDtoy,

Thank you for your helpful information! Unfortunately, I don't have experimental literature data at hand right now.

hi James and CFDtoy
i am working with 2 phase model of solidification/melting.
which is "solidification in rectangular enclosure"
do you have any literature regarding the procedure for application of the boundary conditions?
i got tutorial of continuous casting but for further problems it is not that useful.
only solid/melting model is used or in addition to this any other model is required.
will be very thankful to you.
