TL;DR: In this article, an experimental investigation was carried out for fluid flow and heat transfer in the case of an elliptical duct rotating about a parallel axis using air as the working medium.
Abstract: Experimental investigation was carried out for fluid flow and heat transfer in the case of an elliptical duct rotating about a parallel axis using air as the working medium. It was found thai the increase in heat transfer (due to rotation relative to the stationary condition) for an elliptical duct lies between the values for a circular duct and those for a square duct for fully developed laminar and turbulent flows. It was observed that elliptical ducts are more advantageous from the viewpoint of heat transfer augmentation.

TL;DR: In this article, the combined heat transfer of convection and radiation in rectangular ducts rotating in a parallel mode was investigated numerically in detail, and the coupled momentum and energy equations were solved by the DuFort-Frankel numerical scheme to examine the interactions of the convection with radiation.

TL;DR: In this article, rotation-induced secondary flow and mixed convection heat transfer in the entrance region of rectangular ducts rotating about a parallel axis are investigated. And the authors show that the rotational effect in an iso-flux duct is more significant than that in an isothermal flux, while the effect vanishes in isothermal ducts.
