Abstract

An experimental study of gas liquid flow in an inclined circular pipe was performed. Experiments were performed for two values of superficial liquid velocities and different gas flow rates. The angle of pipe inclination varies from 10° to 80° with respect to horizontal position. Wall shear stress was measured in the apex point of the pipe using an electrodiffusional technique. A strong effect of pipe inclination on wall shear stress was shown. The highest values of wall shear stress corresponded to the angles of 40° to 60°. A significant increase of wall shear stress at low gas flow rates was detected.

倾角对管道中向上两相流的壁面剪应力的影响

摘要对倾斜圆管中的气液流动进行了实验研究。实验采用了两种表面液体速度值和不同的气体流速。与水平位置相比，管道的倾斜角度从 10° 到 80° 不等。使用电扩散技术在管道顶点测量了管壁剪应力。结果表明，管道倾斜度对管壁剪应力有很大影响。管壁剪应力的最高值与 40° 至 60° 的角度相对应。在气体流速较低时，管壁剪应力明显增加。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
