摘要：
The process of outflow of a high-enthalpy flooded gas stream from the slotted outlet of a direct current plasmatron is experimentally studied. Using the laser optical shadow method, the outflow pattern was visualized in two mutually perpendicular planes of the jet. A method was proposed for processing digital images of the jet, which made it possible to determine the boundaries of the jet, the angles of its opening and their dynamics - the average values of the angles were (19 ± 2)° and (11 ± 2)° in the planes along and across the long side of the slit, respectively. Based on the data obtained, the outflow mode was determined and compared with known literature data. © 2024 ORION Research-and-Production Association. All rights reserved.
