Hi,

I am trying to simulate (transient) ice formation/solidification in a pipeline with the following conditions:

inlet velocity: 1.5 m/s
water inlet temperature: 278 K
pipe outside surface temperature: 233 K


I tried the "Solidification/melting" mode in fluent without pull velocity, but solution did not converge.

I tried the "Solidification via Temp-dependent viscosity" example using a UDF to assign higher viscosity for temperature below 273 K. But I faced convergence errors.

In both the cases I used k-epsilon for viscous model.

Does the convergence problems occur due to the viscous model?

Or is there any other method to simulate water-ice solidification in a pipeline using Fluent??

Thanks!!

Did you solved it?
I am trying to solve the same problem!
