...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...

... it relates to smaller flow resistance too. The outer and inner diameters of the tube introduced in Ref. [ 26 ] are 72 mm and 68 mm, respectively. The outer diameter of the LBFT is 19 mm. The smaller size of tube involves larger pressure loss. Compared with the case in Ref. [ 26 ], the advantage of the higher...

...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...

...) to the chaotic flow improved heat transfer by 4–14% and 4–18%, 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...

...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...
