Polytropic, differentially rotating cylinders
American Journal of Physics, 1981Infinite cylinders composed of polytropic material can possess nearly arbitrary rotation fields while retaining the fundamental simplicity of one-dimensional structures. The physical properties of these objects can be easily calculated and understood by junior–senior level physics students even without access to a large computing facility.

Relativistically rotating dust cylinders
Journal of Mathematical Physics, 1977A previously derived method for obtaining the general differentially rotating dust metric is applied to the cylindrically symmetric case. The dust metric, the exterior vacuum metric, the matching conditions at the boundary, and the asymptotic behavior at infinity are worked out explicitly.

Rotating Convection in a Finite Cylinder
Applied Scientific Research, 1993When a rotating circular cylinder containing fluid is heated from below, it is observed that azimuthally travelling waves may appear in the fluid. A linear stability model is described whose numerical solutions agree well with experimental observations.

Viscoelastic shear flow past an infinitely long and freely rotating cylinder
The Physics of Fluids, 2018We study analytically the effect of steady shear flow on an infinitely long and freely rotating circular cylinder using asymptotic methods. The ambient fluid is assumed viscoelastic and modeled with the Oldroyd-B constitutive equation under isothermal ...
