TLDR
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.About:

Rotating metal foam structures for performance enhancement of double-pipe heat exchangers
TL;DR: In this article, a compound enhancement is proposed incorporating both active and passive methods to enhance the amount of heat transported in a double-pipe heat exchanger by using metal foam guiding vanes, which are fixed obliquely and rotating coaxially.

The relationship between absolute vorticity flux along the main flow and convection heat transfer in a tube inserting a twisted tape
TL;DR: In this article, the relationship between the intensity of the secondary flow and laminar convective heat transfer was studied using a numerical method, and it was shown that the cross-averaged absolute vorticity flux in the main flow direction can reflect the intensity intensity of secondary flow.

Developing convective flow in a square channel partially filled with a high porosity metal foam and rotating in a parallel-mode
TL;DR: In this paper, the development of three-dimensional heat transfer and fluid flow in a square channel rotating in a parallel mode has been investigated numerically, and the generalized model is used to mathematically simulate the momentum equations employing the Boussinesq approximation for the density variation.

Combined mixed convection and radiation heat transfer in rectangular ducts rotating about a parallel axis
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.

A calculation procedure for heat, mass and momentum transfer in three-dimensional parabolic flows
S.V. Patankar,D. B. Spalding +1 more
TL;DR: In this article, a general, numerical, marching procedure is presented for the calculation of the transport processes in three-dimensional flows characterised by the presence of one coordinate in which physical influences are exerted in only one direction.

TL;DR: In this article, the authors presented a fully developed fluid flow problem for rectangular ducts, where the flow field in a noncircular duct having corners is divided into as many numbers of flow regions as there are corners.
