Why would I need to assume that? Heat flows from warmer objects to colder objects. Cold does not flow at all.No one who understands thermodynamics will agree with you on this. You said it yourself, cold is the absence of heat. Heat is not the absence of cold.
You're assuming that all fluid mechanics are Newtonian.
Why? Why are you doing that?
The temperature of an object is the measure of the heat energy that it contains. More energy equals a higher temperature; less energy equals a lower one.
"...There is no such thing as “cold”. When you touch a piece of ice with your bare hand, the sensation that you feel is not the presence of “cold”, it is the subtraction of heat. The more rapidly you withdraw heat the more “cold” it feels. The ice has such little heat compared to your body that the heat rushes from your hand to balance things out. Your hand continues to lose heat rapidly until the ice is melted, then and only then can your hand warm back up. The sensation that you feel in your hand, through your brain, is that of heat being sucked from your body. Your brain detects this and calls it “cold”but in reality it is simply the profound lack of heat..."
