SUMMARYIn this paper, we consider edge-based reconstruction (EBR) schemes for solving the Euler equations on unstructured tetrahedral meshes. These schemes are based on a high-accuracy quasi-1D reconstruction of variables on an extended stencil along the edge-based direction. For an arbitrary tetrahedral mesh, the EBR schemes provide higher accuracy in comparison with most second-order schemes at rather low computational costs. The EBR schemes are built in the framework of vertex-centered formulation for the point-wise values of variables.Here, we prove the high accuracy of EBR schemes for uniform grid-like meshes, introduce an economical implementation of quasi-one-dimensional reconstruction and the resulting new scheme of EBR family, estimate the computational costs, and give new verification results.

In this paper, the results of numerical and experimental studies of the acoustic efficiency of a group of prismatic resonators of different volumes at an acoustic pressure level of 130 dB were presented. The prototype was developed, and representative samples of fragments of different-height sound-absorbing structures were manufactured by 3D-printing. Laboratory tests of the samples were carried out on the interferometer with normal incidence of sound waves. The acoustic efficiency of the developed sound-absorbing structures was experimentally confirmed. The different-height sound-absorbing structures allow to extend the broadband of the prismatic resonator group.

In this work the physical and mathematical models of predicting the effective acoustic properties of sound absorbing structures (Helmholtz resonators) in joint operation were formulated. Numerical simulation has been performed on the modeling of an acoustic wave in a model channel with resonators of various configurations. Research was carried out to optimize the mutual arrangement of Helmholtz cells (resonators) in sound-absorbing structures of resonant type. According to the results of the research, the mutual influence of closely located prismatic resonators in the model channel of rectangular shape was revealed. The most effective combinations of prismatic resonators were determined. Schemes and recommendations for the placement of composite and base resonators in sound-absorbing structures were developed. Unique single-layer composite sound-absorbing structures, working at several resonant frequencies, were developed. , 0 (2018) MATEC Web of Conferences
