Научный вестник МГТУ ГА, 2023 Spline couplings, due to their high reliability and strength parameters, are widespread not only in mechanical engineering. The ability to transmit high torque with a sufficiently long service life has led to the extensive use of these couplings in the ...

Proceedings of the National Academy of Sciences, 1973 114 temperature sections, each containing an average of 10 bathythermograms, show that internal waves commonly become altered on crossing the shoaling bottom of the continental shelf in Santa Monica Bay, Calif. The alteration takes the form of internal swash (in which the lower isotherms reach farther landward than would be expected from their depth ...

Influence of Beach Slope on Morphological Changes and Sediment Transport under Irregular Waves
Journal of Marine Science and Engineering, 2023 This paper presents new data from large-scale wave flume experiments. It shows the beach profile evolution and sediment transport for two different bed slopes (1:15 and 1:25), and three irregular high-energy erosive wave conditions and one low-energy ...

A Conceptual Model for Spatial Grain Size Variability on the Surface of and within Beaches
Journal of Marine Science and Engineering, 2016 Grain size on the surface of natural beaches has been observed to vary spatially and temporally with morphology and wave energy. The stratigraphy of the beach at Duck, North Carolina, USA was examined using 36 vibracores (~1–1.5 m long) collected along a

Storm Waves at the Shoreline: When and Where Are Infragravity Waves Important?
Journal of Marine Science and Engineering, 2019 Infragravity waves (frequency, f = 0.005–0.05 Hz) are known to dominate hydrodynamic and sediment transport processes close to the shoreline on low-sloping sandy beaches, especially when incident waves are large.

SWASHES: A Library for Benchmarking in Hydraulics [PDF]
, 2013 Numerous codes are being developed to solve shallow water equations. Because they are used in hydraulic and environmental studies, their capability to simulate properly flow dynamics is essential to guarantee infrastructure and human safety. Hence, validating these codes and the associated numerical methods is an important issue.

Chinese Journal of Mechanical Engineering, 2020 The interface between the slipper/swash plate is one of the most important frication pairs in axial piston pumps. The test of this interface in a real pump is very challenging. In this paper, a novel pump prototype is designed and a test rig is set up to
