The artificially submerged cavitation water jet is effectively utilized by ejecting a high-pressure stream into low-pressure through concentric nozzles and utilizing the phenomenon generated shear layer formed between two streams. In this study, we investigated characteristics of jets combining numerical simulations erosion experiments. results indicate that an appropriate standoff distance can generate more clouds on workpiece surface, are most pronounced at dimensionless SD = 30. effect...
The hydrodynamic performance of a novel hovering autonomous underwater vehicle, the helicopter (AUH), with an original disk-shaped hull (HG1) and improved fore–aft asymmetric (HG3), is investigated by means computational fluid dynamics adoption overlapping mesh method. two shapes in surge motion variation angle attack compared. results show that HG3 has less resistance higher stability compared to HG1. With reaching 10 degrees, both HG1 achieve maximum lift-to-drag ratio, which for...
This paper systematically investigates the electronic structure and optical properties of zinc-blende ZnTe, ZnS systems, ZnTe/ZnS heterojunctions, Y-doped heterostructions using generalized gradient approximation (GGA) method under density functional theory (DFT) framework. The results show that compared to single-component ZnTe or heterojunction has a smaller bandgap width undergoes redshift in absorption spectrum, which is favorable for more valence band electrons be excited by light...
Abstract In this study, a sediment isobaric transfer device based on the principle of volume displacement was built, and work process explained. A physical model built in hydraulic analysis software AMESim to simulate actual working conditions. The influences pre-charge pressure accumulator, diameter, length pipeline opening safety valve fluctuation steady-time during were studied. system optimally designed results parametric analysis. sea trial verified that could with exceeding 90 MPa into...
The hydrodynamic characteristics of the disk-shaped Autonomous Underwater Helicopter (AUH) cruising near free surface were investigated using a computational fluid dynamics approach. influence velocity, depth, wave height and wavelength considered. changes force AUH mainly by influencing pressure distribution AUH. Meanwhile, depth velocity also affect flow law surface. For cases without waves, decrease will lead to generation resistance, thus increasing time-average fluctuation range...
