Thanks MortenA & Chicopee, I agree that the pressure and ice temperature are coupled and I have a vacuum pump to remove the vapour. My feeling about the whole process is that the increase in temperature of the steel jacket will lead to an increase in the ice temperature and an increase in the...

Hi EdStainless, Thanks for your response The first value are assumptions of the state of the system and not calculated - so I have no equation. Secondly, I feel conduction from the wall to the ice is the dominant heat transfer mechanism and radiation is minimal. The ice is in contact with the wall.

Hello all, I am trying to solve a sublimation/heat transfer problem and could use some help from you. I have a freeze dryer under vacuum at a pressure of say 0.1 mbar. The temperature of the ice in the dryer is say -20 degree centigrade (253 Kelvin). To assist sublimation, I am providing heat to...
