Superrotation is shear flow on gas planets and stars and it requires an explanation since there appears to be no force or stress to drive them. Recently I came up with the following idea after having tried two others with limited success.
Assume that gas or matter flowing along planets' or stars' rotation around its axis is less affected by viscous drag compared to flow going against the. This is because of differences in centrifugal acceleration between these two cases. Matter being less affected by gravity due to centripetal acceleration pushes less on the underlying matter and will have its viscous shear stress reduced. In a gas or other fluid with thermal motion there will be particles moving in any direction and they will be slowed down differently depending on direction of motion relative the rotational direction. How could this be quantitatively determined? If another more practical and smaller size example helps you to better imagine the physical situation you can think of a gas centrifuge for uranium enrichment. There should be high shear flow in that case as well and not as we are erroneously informed on various places on Internet that there is solid body rotation. Does anyone here think it is correct to lie about physics in order to stop understanding of it and thus prevent proliferation of technologies based on the effect? It is both impressive and disgusting that someone has been capable of keeping this kind of physics undeveloped for over a century. It would have been natural to see this combination of fluid mechanics and thermal physics to appear soon after the appearance of kinetic gas theory. Now with bin Ladin killed maybe physics can flourish a bit further. David David Jonsson, Sweden, phone callto:+46703000370
