Kurzbeschreibung (Abstract)
The effects of tube rotation on the velocity and temperature distribution, on the friction coefficient and on the heat transfer to a fluid flowing laminar inside a tube are examined by analysis. It is demonstrated that the rotation has a destabilizing effect on a laminar pipe flow, which changes to turbulent flow. Free convection vortices, that occur, if the pipe wall is heated, disappear with a growing rotation velocity of the tube. For that purpose a perturbation calculation is performed. By the results of this calculation the disappearance of the free convection vortices is demonstrated evidently.
