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.
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.
