- Title
Buoyancy waves as a thermal pump.
- Authors
Merkulov, V. I.
- Abstract
The joint effect of thermal conductivity, viscosity, and of an ascending flow on the thermodynamic processes proceeding in buoyancy waves in a compressible medium is analyzed. It is shown that in this case the waves act as a thermal pump that transfers heat from the upper cold layers of air to the lower warmer ones, thus creating and sustaining a negative temperature gradient. This allows one to adequately explain the temperature stratification observed in the atmosphere and in Ranque–Hilsch tubes.
