Special Cases of Using Visualization Technology for Analyzing the Dynamics of Gaseous Environment

Abstract

A new visualization technology is presented, which was used in applied research when observing and modeling the dynamics of the flow of gaseous environments. In the process of developing and improving the technology, a set of experimental results was compiled to study the phenomenon of combustion and detonation of a hydrogen-oxygen mixture, as well as the phenomena of propagation, action, and interaction of shock waves and gas-dynamic structures. On the example of analyzing data on the dynamics of the formation of a vortex ring, the possibilities of verifying the computational model of the implemented physical process are shown. The presented results reflect the level of information content when using technology to carry out tests.

Estimation of the average density of air in a model fire tornado based on laser transmission data

“…Therefore, it seems relevant to develop methods and means for measuring the gas-dynamic characteristics of matter in the core of a vortex. To date, there are many optical methods for studying the burning volume: active [3][4][5][6][7] (various modifications of PIV, V3V) for measuring the velocity field, and passive [8][9][10][11][12][13] (imaging in the UV, visible and IR ranges) for measuring the temperature field. Information about the density of matter in the inner regions of the tornado is based on the results of measurements of other characteristics and mathematical models that, to one degree or another, describe the processes occurring in the fire whirlwind.…”
