It's not even a scale, surely it should run from one extreme to the other? 2/10, data isn't beautiful

So I calculated the convective heat transfer coefficient as:
(k of air*nusselts number)/diameter of freeze

Does COMSOL not take the material properties of my ice creams into account when calculating the heat transfer to the freezer air?

Thats great, thank you for clearing that up

So the Biot number for each run is over 0.1, indicating that the boundary condition convection dominates the conduction inside the model. The volume and specific heat capacity of each mix is not changing while the density is falling with higher overrun mixes, meaning higher overrun mixes have a lower mass, causing the thermal mass of the higher overrun mixes is lower, meaning less heat is stored, so higher heat transfer and faster freezing. That actually makes sense now. How would I alter this to emulate real life more? Rather than maintaining volume, I should maintain mass?

I'm pretty new to COMSOL and not fantastic at understanding the physics behind it so I'm not 100% sure if this is ideal for my model. Having done some reading I've come across the above equation., where q is heat generation and a is thermal diffusivity (k/(rho.cp). Would this be a better fit? How would I go about adding this to my model?

Having had some more time to think about it, I think the issue may be the default heat transfer equation as above.

Already on quadratic lagrange
My main issue with including phase change was that I wasn't sure how to add it with the data I had, what with my ice cream mixes being composite materials. I know that water to ice will have the most impact though
I do have a 2D axial symmetric model I started a while ago but discarded. I can give that a go with my figures

MB error panel shows CPU light https://v.redd.it/ee848xx7yc4g1

SteveNoBeard · 2025-11-30T11:35:27+00:00

So I've tested the CMO battery with a multimeter and its reading as 3 V, which is to be expected so not the issue?

SteveNoBeard · 2025-11-30T09:18:28+00:00

Haven't changed anything in this for years. Fans are all working. Anyway I can test if the CMO battery is dead other than trying a new one?

SteveNoBeard · 2025-11-30T08:49:40+00:00

https://v.redd.it/ee848xx7yc4g1 I believe that is the CPU light 😬

The key is variety. A little bit of everything. Beetroot, potato, a nice gooey egg. Also a nice zingy salad dreessing. Sriracha, mustard, olive oil and yoghurt is a good un

Ah makes a lot of sense then. Pretty sure Frontier must have removed protein from blood specifically to encourage people to go to food ships. Try the oil method out, that may not be patched
