The concepts its like air cooler portable
@ Auliya, I think no, as for rapid cooling of such volumes needs intense stirring . Liquid nitrogen tends to stay on top of the heavier water and evaporates very easily as it may form an ice layer with rest of the liquid.
Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

As it is highly probable that pellets will have a higher degree of air gaps and voids than thin films, is it possible to pole the samples with corona poling nevertheless? Or is there the...

Dear all, My research group is currently working with a 12-litre fermenter. Somehow, if we do the fermentation for more than 20 hours, the process will be more prone to contamination. Our current...
