Visualization of a subsonic nonisothermal jet
Abstract
The objective of the study was to develop a method for visualizing low-velocity jets that would provide quantitative and qualitative characterization of coherent structures. The study was conducted in a wind tunnel with a 20-mm-diameter nozzle, with the initial jet velocity varying from 16 to 50 m/s and a jet temperature of 31 C at the nozzle exit section. The visualization was carried out using an experimental shift interferometer. The characteristic features of the visualized coherent structures are discussed.
