Flow and heat transfer is considered between two rotating spheres with constant angular velocities....

or counter-clockwise at a constant angular velocity. The effects of parameters such as the eccentricity of the axes, the Rayleigh number and rotation direction were studied. The two-dimensional Navier-Stokes and energy equations were numerically solved...

Flow and heat transfer is studied between two concentric spheres when they are rotating with time-dependent angular velocities....

Analytical solution of flow between two rotating spheres with time-dependent angular velocities....

Numerical study of mixed convection in an annulus between concentric rotating horizontal cylinders is presented in this work by using finite volume method. The mixed convection is due to natural convection because of ...
