Abstract

In solar applications, research into appropriate methods to improve the performance of the solar water heater is important. The current work studies improved the performance of the solar water heater by analyzing the effect of the number of added tape twists. A four-pipe solar water heater was built, and four twisted tapes were used, each with a different number of twists (flat, one, three, and five twists), and each tape was inserted into a pipe. The addition of twisted tapes has found that improved the performance of the solar water heater, and this improvement increased with the number of twists. A one, three, and five-twisted tapes achieved a temperature increase of (5.33, 14.09, and 20.27%) respectively, relative to a flat tape, and the instantaneous efficiency of the five twists tape was the highest, where the highest instantaneous efficiency of the four types rates (9.6, 13.4, 13.8, and 15 %) respectively.

缠绕胶带数量对太阳能热水器性能的影响

在太阳能应用中，研究适当的方法来提高太阳能热水器的性能是很重要的。目前的工作研究是通过分析增加胶带缠绕次数对太阳能热水器性能的影响来提高热水器的性能。建造了一个四管太阳能热水器，使用了四个扭曲的胶带，每个都有不同的扭曲次数(平的，一，三，五)，每个胶带都插入管道中。研究发现，加扭带提高了太阳能热水器的性能，而且这种改善随着扭带的增加而增加。一捻、三捻和五捻胶带相对于平捻胶带的温升分别为5.33、14.09和20.27%，五捻胶带的瞬时效率最高，其中四种胶带的瞬时效率最高，分别为9.6、13.4、13.8和15%。

期刊介绍： The International Journal of Integrated Engineering (IJIE) is a single blind peer reviewed journal which publishes 3 times a year since 2009. The journal is dedicated to various issues focusing on 3 different fields which are:- Civil and Environmental Engineering. Original contributions for civil and environmental engineering related practices will be publishing under this category and as the nucleus of the journal contents. The journal publishes a wide range of research and application papers which describe laboratory and numerical investigations or report on full scale projects. Electrical and Electronic Engineering. It stands as a international medium for the publication of original papers concerned with the electrical and electronic engineering. The journal aims to present to the international community important results of work in this field, whether in the form of research, development, application or design. Mechanical, Materials and Manufacturing Engineering. It is a platform for the publication and dissemination of original work which contributes to the understanding of the main disciplines underpinning the mechanical, materials and manufacturing engineering. Original contributions giving insight into engineering practices related to mechanical, materials and manufacturing engineering form the core of the journal contents.
