Thermal Buoyancy Effects in RotatingNon-Isothermal Flows
TLDR
In this paper, the rotation-induced thermal buoyancy effects stemming from the coexistence of rotational body forces and the nonuniformity of the fluid temperature field are considered.Abstract:
The present paper is concerned with the non-isothermal flow mechanisms in rotating systems with emphasis on the rotation-induced thermal buoyancy effects stemming from the coexistence of rotational body forces and the nonuniformity of the fluid temperature field. Non-isothermal flow in rotating ducts of radial and parallel modes and
rotating cylindrical configurations, including rotating cylinders and disk systems, are considered. Previous investigations closely related to the rotational buoyancy are surveyed.
The mechanisms of the rotation-induced buoyancy are manifested by the author's recent theoretical results and scaling analyses pertaining to the rotation-induced buoyancy in rotating ducts and two-disk systems. Finally, the open issues for future researches in this area are proposed.read more

On the flow between two rotating coaxial disks
TL;DR: In this article, the steady motion of a viscous fluid confined between two coaxial rotating disks is discussed both experimentally and theoretically, and it is found experimentally that when the disks rotate in the same sense, the main body of the fluid rotates as well, but if they rotate in opposite senses, the fluid is almost at rest.
