- TL;DR Summary
- Would air, given a truly closed system, stratify by temperature? Is the stack effect relevant to closed systems, or is it specific to outside reference?
In thinking about temperature stratification of air: I assume that in a truly closed system with no heat inputs, air would NOT stratify by temperature.
On the other hand, a heat source introduced in a closed container would generate stratification while it was generating heat (and following for a time). It would then trend towards equilibrium (diffusion, entropy, etc.)
So temperature stratification is dependent on a dynamic system, and the trend is towards equilibrium: remove the source of heat, and stratification will actually REDUCDE not increase.
Yes?
Therefore, the more isolated a system is, the less temperature stratification we will observe. Yes?
Therefore, the 'stack effect' is a term most relevant to open systems. Indeed it is sometimes referred to as chimney effect, which implies a communication between two... steady states?
