Wärmeübertragung in einem axial rotierenden, durchströmten Rohr im Bereich des thermischen Einlaufs Teil 2: Einfluß der Rotation auf eine laminare Strömung.
In: Wärme- und Stoffübertragung, 24 (5), pp. 273-278. [Article]

Abstract

The effects of tube rotation on the temperature distribution and the heat transfer to a fluid flowing inside a tube are examined by analysis in the thermal entrance region. The flow is assumed to be hydrodynamically fully developed. The rotation has a destabilizing effect on the laminar pipe flow, causing a transition to turbulent flow. Therefore, a remarkable increase in heat transfer with increasing rotational Reynolds number can be observed. The thermal entrance length decreases remarkably with growing rotational Reynolds number.
