Busse theory of ultimate heat transfer limit

WebDuring processing, temperatures may change and therefore the rate of heat transfer will change. This is called unsteady-state heat transfer, in contrast to steady-state heat transfer when the temperatures do not change. An example of unsteady-state heat transfer is the heating and cooling of cans in a retort to sterilize the contents.
