Note on the effect of rotation on diffusion processes

Article English OPEN
Welander, Pierre (2011)

A gas in solid rotation that is subjected to a radial temperature gradient develops a component of heat diffusion at right angles to the gradient. The magnitude of this diffusive flux, relative to the radial component, is 2λΩ/v?, where λ and v? are the mean free path and the mean radial speed of the molecules, respectively, and Ω is the angular velocity of the system. Corresponding effects occur in diffusion of mass and momentum. It is suggested that the same effect becomes important in the large-scale turbulent transports in the atmosphere and the oceans. The prediction is that a general eastward eddy heat flux should occur.DOI: 10.1111/j.2153-3490.1966.tb01444.x
