...Fei Li; Chenglan Xiong; Yu Rao; Yong Luan; Bernhard Weigand The paper presents a numerical study of the heat transfer, pressure loss, and flow characteristics of swirl cooling in elliptical tubes, which are compared to the counterpart of swirl cooling in a circular tube with a diameter of D = 50.0...

... tube. Hence, the enhanced convective heat transfer performance of the LBFT also accompanies with more cost of pressure loss. Compared with a smooth tube, it is apparent that the disturbance from the pores, the bridges, and the bridge roots of the LBFT results in more pressure loss. While the structure...

...Yu Rao; Zhongqiu Guo; Deqiang Wang Detailed experimental and numerical studies have been conducted on the heat transfer, pressure loss, and turbulent flow structure of a three-short-pass serpentine cooling channel with miniature W-shaped ribs on the wall under the Reynolds numbers from 8500...

...%, respectively, with a marginal increase in the pressure drop. chaotic advection nanofluids laminar flow pressure loss heat transfer There are various methods for heat transfer enhancement, which can be categorized into two general groups: (1) passive methods requiring no external force and (2...

...Ken Ogiso A method of assessing the overall cooling performance in the thermal design of electronics is presented. The method is based on the optimization concept proposed by A. Bejan, whose original idea was related to the trade-off between heat transfer enhancement and pressure loss increase...
