It is shown that for supersonic flows, in addition to the Mach waves described by Kovasznay, generated by stationary sources of disturbances on the walls of the test sections, and Mach waves generating the most intense fluctuations, distributed and moving in a supersonic turbulent boundary, described by Laufer, there may be Mach waves, the sources of which are sounds, as well as a turbulent boundary layer. Using the hot-wire approach, it is possible to determine the characteristics of each type of these waves and their source. It is also established that simple sound waves can be produced by the turbulent boundary layer and penetrate into the leading part from sources launched in the prechamber of the wind tunnel to the critical section of a Laval nozzle. In high-subsonic-speed wind tunnels, acoustic disturbances are produced from sound waves identified by intensity, direction and spectral composition using developed methods of thermal anemometry. The characteristics of acoustic disturbances (intensity, direction, location of sources) determined using the hot-wire method allow them to be purposefully preserved or reduced, or their influence on phenomena under investigation can be taken into account.

Visualization of the microstructure in acoustic microscopy in reflection mode is provided by recording signals during reflection or scattering of the ultrasound beam on the elements of the internal structure. Some of the elements can be acoustically rigid thin cylindrical scatterers. The radius of thin cylindrical elements is significantly smaller than the size of the focal spot of the probing beam, therefore, all thin elements of small diameter are displayed in acoustic images with the same size equal to the diameter of the focal spot. To estimate the sizes of thin cylindrical elements visible in the images, a theoretical approach is proposed that describes the formation of the amplitudes of output signals during the interaction of a focused ultrasound beam with thin cylindrical elements of the structure. The analytical description of the interaction takes into account the radius of the element and the sensitivity of the receiving acoustic system. Taking into account the parameters of the emitter/receiver and the geometry of the cylinder, the inverse problem of estimating the scatterer size depending on the received signal is solved. The theoretical approach is experimentally confirmed by visualization of thin polymer fibers using a scanning pulse acoustic microscope and acoustic lenses at frequencies of 50 and 200 MHz, forming focused beams of different geometries. Based on the results of comparison of experimental data and theoretical calculations, a conclusion is made about the applicability of the described analytical approach within the framework of assumptions and approximations for long-focus beams with a small-angle aperture when estimating the minimum dimensions of cylindrical scatterers visible in acoustic microscopy.</div>","PeriodicalId":455,"journal":{"name":"Acoustical Physics","volume":"71 4","pages":"550 - 558"},"PeriodicalIF":1.2,"publicationDate":"2025-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1134/S1063771025600275.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145561229","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Calculations are performed for several relative positions of both rotor blade rows and stator blade rows. The considered computational model includes a row of fan rotor blades, rows of rotor blades, and rows of stator blades corresponding to the first two booster stages, as well as a row of inlet guide vanes of the booster. The stages have identical numbers of rotor blades and stator blades. The problem is to obtain the power of noise radiation and directivity patterns for the most intensive tones in operating mode (bar {N}) = 58%. The investigation is performed using a method of multistage turbomachine tonal noise calculation in the frequency domain. The method is capable of modeling a change in the relative position of blade rows without any manipulations with a computational grid. The results of calculations show that clocking of rotor blade rows can change the power of radiation from the inlet by 4 dB. Clocking of stator blade rows has a negligible influence on the total power of noise radiation from the inlet, though for some circumferential modes, the power can change by more than 5 dB.

A theoretical model of the structure is established using the transfer matrix method, and a simulation model is constructed with COMSOL software. The accuracy of the results is verified through sound absorption experiments. By analyzing the sound absorption mechanism and exploring the influence of structural parameters on sound absorption performance, the results indicate that front-perforation induces a pressure diffusion effect, effectively enhancing acoustic energy dissipation and improving sound absorption. By adjusting the radius of front-perforation, a balance between the pressure diffusion effect and acoustic energy dissipation in the matrix material can be achieved, thereby maximizing sound absorption performance. When the perforation radius exceeds 7.5 mm, the sound absorption performance of aluminum foam with side perforations is significantly superior to that with front perforation. The perforation diameter on the incident surface significantly influences sound absorption, resulting in similar performance between the inverted gradient perforation dual-porosity aluminum foam (IG-DPAF) and the “I-shaped gradient” perforation dual-porosity aluminum foam, both demonstrating excellent broadband sound absorption properties with absorption coefficients exceeding 0.8 across the frequency range of 1000–6300 Hz. Conversely, the sound absorption behavior of the positively gradient perforated dual-porosity aluminum foam (PG-DPAF) resembles that of the “+shaped gradient” perforation dual-porosity aluminum foam in terms of sound absorption behavior. This study provides novel insights for the structural design and performance optimization of aluminum foam-based sound-absorbing materials.","PeriodicalId":455,"journal":{"name":"Acoustical Physics","volume":"71 4","pages":"517 - 530"},"PeriodicalIF":1.2,"publicationDate":"2025-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145561550","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, a three-layer membrane-type acoustic metamaterial (MAM) is introduced as a potential solution. Through orthogonal experiments, remarkable sound insulation capabilities are demonstrated within the frequency range of 100–1200 Hz. By analyzing the eigenmodes and sound transmission loss (STL) at resonance and anti-resonance frequencies, the underlying sound insulation mechanism of the three-layer MAM is clarified. In addition, an orthogonal experiment is utilized to identify the key factors affecting sound insulation performance. Using relative bandwidth as the classification criterion, the optimal combination of influencing factors is identified, leading to improved STL performance of the multi-layer MAM and broadening the sound insulation bandwidth.

Wave transmission behavior is investigated in both magnetically open (MO) and magnetically closed (MS) circuit boundary circumstances. The primary study focuses on the scattering behavior of phase velocity in a Love-type wave as influenced by the combination of VL, PM, and HHS. The dispersion relation for Love-type waves was calculated analytically, and phase velocity graphs were displayed and evaluated using Mathematica software. A detailed investigation was undertaken to determine the influence of important variables on phase velocity, such as material heterogeneity, piezomagnetic coupling, and viscous liquid layer thickness. The research results demonstrate the influence of VL, PM, and HHS materials on phase velocity in MO and MS conditions. Graphical comparisons reveal that piezomagnetic coupling causes significant changes in phase velocity, highlighting its role in wave propagation. The open and short circuit conditions exhibited approximately similar phase velocities, suggesting that boundary constraints had a negligible effect on wave propagation. The model only considers linear wave transmission and excludes nonlinear effects. Furthermore, the technique is predicated on idealized material properties that account for heterogeneity. The findings can be used to design and develop energy harvesters, sensors, and wave manipulation instruments using PM with viscous liquid coatings. Understanding the behaviour of surface waves, including phase velocity, is essential for efficient application in these frameworks.","PeriodicalId":455,"journal":{"name":"Acoustical Physics","volume":"71 4","pages":"569 - 579"},"PeriodicalIF":1.2,"publicationDate":"2025-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145561230","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
