Abstract
The work presents development of a technique for measurement of the local parameters of a near-wall liquid film (film thickness, leading edge velocity, and wave velocity on the film surface) under conditions of a co-current supersonic gradient gas flow. The parameters of an ethanol film with a co-current air flow inside a supersonic conical nozzle with the Mach number M = 2.75 were measured. The decisive role of the gas flow on the parameters of the near-wall film has been shown. It has been established that phase transitions appear in the liquid film within the nozzle because the static pressure in the gas flow over the film drops below the saturated vapor pressure of the liquid.
期刊介绍:
Journal of Engineering Thermophysics is an international peer reviewed journal that publishes original articles. The journal welcomes original articles on thermophysics from all countries in the English language. The journal focuses on experimental work, theory, analysis, and computational studies for better understanding of engineering and environmental aspects of thermophysics. The editorial board encourages the authors to submit papers with emphasis on new scientific aspects in experimental and visualization techniques, mathematical models of thermophysical process, energy, and environmental applications. Journal of Engineering Thermophysics covers all subject matter related to thermophysics, including heat and mass transfer, multiphase flow, conduction, radiation, combustion, thermo-gas dynamics, rarefied gas flow, environmental protection in power engineering, and many others.
