Hello All,

I am doing some analysis, In which i am facing some situation like, There is water or any liquid inside the metal box and the liquid gets frozen in transient manner. How can i handle this phase transformation, with what kind of element and solver?

Please give me some hint of approach in order handle this kind of problem.

I am beginner in operating ANSYS. I am using ANSYS classic

Thanks a lot in advance.

Firstly all post to XANSYS must have a signature showing your full name
and company; please ensure you comply in future.

It might help if you explain the purpose of the analysis. Are you
trying to do a thermal analysis (eg to predict how much ice is formed)
or a structural analysis (to predict stresses due to change of volume as
water turns to ice)?

Hey Martin,

Thanks for your reply. Yes, Unfortunately, I forgot to write signature with full name. However, i have corrected it. You will see signature now on.

I wanted to do structural analysis where i wanted to see the effect of structure due to volume change as water turn into ice.

(It would also be helpful, if you explain some way of approach which stated in tutorial to deal with it)

Regards,
Rohan

Hello,

In my opinion, you could perform a hand calculation of volumetric expansion
of ice.
Imagining an ice cube, you will have a delta_a, delta_b and delta_c (the
cube dimensions variation).
Then, apply this displacement to your structure.
This can be an initial approach...

That's exactly what he ought to be doing. Water gets a little tricky
around the freezing point because it expands as it freezes, unlike
most substances. That's why the ice cubes float in a gin and tonic.
Entering those properties correctly and accounting for the latent
heat effects isn't something a newbie should get into before trying
to figure out how ANSYS might do it.

Dear Mr.Rohan,

i have some slides on ansys training explaining how to calculate
solidification and melting. i tried to send you those slides but it bounces
back. if you have other email address let me know. i will send you there.

Thanks
