34. Parametric Research of the Vortex Ring Noise.

Author

Kopiev, V. F. and Khramtsova, I. V.

Abstract

To study the aeroacoustic characteristics of a vortex ring, a piston generator of the vortex rings was developed in the Laboratory of Noise Generation Mechanisms and Modal Analysis. Using this generator, an experimental research of the aeroacoustic characteristics of the vortex ring based on multichannel measurement methods was carried out. During the experiment the acoustic radiation of a single launched vortex ring and the motion of the vortex along a trajectory were recorded. For comparison with the self-similar motion theory, numerical simulation of the vortex ring formation at initial section of the trajectory was carried out with account of the experimentally determined law of the piston motion. The dimensions of the vortex determined by numerical simulation were further used in the self-similar theory. It was revealed a good agreement between the experimental and theoretical values of the characteristic frequency of the free turbulent vortex ring. [ABSTRACT FROM AUTHOR]

Abstract

The concentrations and composition of hydrocarbons - HCs (aliphatic - AHCs and polycyclic aromatic hydrocarbons - PAHs) in the Barents and Kara Seas (cruises 80, 83 and 89 of the R/V «Akademik Mstislav Keldysh», August 2020, June 2021, September 2022 respectively) are analyzed in the paper. The concentrations of the HC dissolved and suspended forms were measured in the surface microlayer (SML, 100-1000 μm thick), melting ice and surface waters. Higher concentration of HCs in SML was found in suspended particulate matter (SPM). AHC concentration in SPM in the Barents Sea were lower (31-96, on average 68 μg/L) than in the Kara Sea in June 2021 (187-1051, 573 μg/L on average), where the studies were carried out in the early summer season. The concentrations of AHCs in the SPM in the SML of the Kara Sea were 3.6 times higher than in the dissolved form (127-217, on average 187 μg/L), and they were almost 15 times higher than those in the surface waters. The accumulation of organic compounds also occurs in ice, but to a lesser extent than in the SML. The composition of alkanes in SML and melting ice mainly indicates the slight influence of autochthonous processes shaping HCs. The average content of PAHs in SPM was also 4.8 times higher than that in the dissolved form. According to the markers, the influence of combustion products of marine fuel was traced in the composition of PAHs. In September 2022, AHC and PAH concentrations in the Kara Sea were lower than in June 2021: on average, 159 μg/L and 492 ng/L accordingly, that is due to a decrease in the content of SPM from an average of 1.89 to 1.21 mg/L., Competing Interests: Declaration of competing interest Authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.
