LDA-Based Experimental Investigation of Velocity Pulsations in the Vortex Tube

Detailed experimental data on the kinematic characteristics of the flow in a vortex tube along its entire length are presented and analyzed. Experimental data obtained in a vortex tube with square cross-section of the working channel were compared at three values of the cold mass fraction: 0.4, 0.5, and 0.75 with the air expansion ratio in the apparatus of \(\pi=5\). The behavior of standard deviations from the mean values of velocity components is analyzed. The noticeable peaks in the percentage of standard deviation from the longitudinal mean velocity component are observed in the area of the near wall flow temperature growth along the tube.

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.
