1Numerical Study of the Intensity Correlation between Secondary Flow and Heat Transfer of Circle Tube-Finned Heat Exchanger with Vortex Generators显示文摘The application of vortex generators in tube-finned heat exchangers is very universal.The vortex generators can generate secondary flow,and as we all know secondary flow can obviously strengthen heat transfer.To use vortex generators much more efficiently in the circle tube-finned heat exchangers,the intensity correlation study between secondary flow and heat transfer is needed.22 different structures of circle tube-finned heat exchangers were numerically studied,including the plain fin cases and the cases with vortex generators.In addition,the influence of fin spacing,transverse and longitudinal tube pitch,heights and attack angle of vortex generators,positions of vortex generators and shape of vortex generators on heat transfer and fluid flow are studied,too.The non-dimensional parameter Se is applied to quantify the secondary flow intensity.The results show that Se can describe the secondary flow intensity very well.There is very close corresponding relationship between overall averaged Nu and volumetrically averaged Se for all the researched cases and the relational expression is obtained.However,there is no one-to-one correlation not only between Re and f but also between volumetrically averaged Se and f for all the studied cases.Yong Guan Wanling Hu Yun Zhang Kewei Song Liangbi Wang 2020Computer Modeling in Engineering & Sciences2020,,4:3
2Genetic Improvement of Betula platyphylla Suk.in China:A Review显示文摘Birch(Betula platyphylla Suk.),distributed in Eurasia,North America,and Australia,is a kind of cold-resistant,fast-growing,and vital pulpwood tree species.It is also one of the most important ecological restoration tree species with high values of economic benefits in Northeast China.To improve the genetic gain and expand the economic benefit of B.platyphylla,many genetic improvements have been carried out.In China,B.platyphylla is widely distributed and varied,and there are many varieties with excellent genetic characteristics.In this paper,the genetic improvement of B.platyphylla was reviewed,and the previous research results were discussed from two aspects:conventional breeding and molecular breeding.Some problems and corresponding solutions in the genetic improvement were put forward to provide ideas for B.platyphylla breeding in the future.Qinhui Zhang Xiaona Pei Lianfeng Xu Xianbo Lu Baoyang Wen Yanlong Li Liankui Wang Guangzhi Dong Wanling Shi Xiaoqing Hu Xiyang Zhao 2022Phyton-International Journal of Experimental Botany2022,91,8:0
