In this study, we theoretically proposed a method to achieve an electromagnetically induced transparency (EIT)-like effect in whispering gallery mode resonator (WGMR) and experimentally validated the lithium niobate (LN) device. Benefitting from electro-optic inverse piezoelectric effects of LN material, two modes WGMR that are close frequency can be tuned at different tuning rates, resulting EIT-like resonance lineshapes. By varying electric field applied WGMR, full dynamic phenomenon...
Numerical modeling of ship bow waves is still hard work, partly due to their multiscale features. Direct three-dimensional (3D) computational fluid dynamics simulation could be an appropriate choice investigate the problem. However, limited by resources, small scale phenomena such as spraying and wave breaking that observed during generation process are usually simplified or not fully distinguished in a 3D simulation. In order accurately capture scales flow field information with available...
Vortex-Induced Vibration (VIV) of multiple cylinders has received increasing attention in the ocean engineering field recent years. In this paper, a two-dimensional numerical model for studying VIV is developed. Based on fixed Cartesian grid with local mesh refinement adopted, immersed boundary method utilized to account existence cylinders. Two-degree-of-freedom single circular cylinder simulated validate model, and then four circular-cylinder group square arrangement. The mass ratio m* =...
Abstract This study conducted a numerical investigation of the flow past linearly tapered cylinder in subcritical regime. concentrated on influence this geometric perturbation and heat transfer characteristics by comparing them with those uniform circular cylinder. It is revealed that effectively reduced mean drag fluctuating lift coefficients. The presented different separation angle locations at spans, gradually moving backward as diameter increased. provided higher Nu than same Re 3000,...
Currently, the hydrodynamic simulation strategies for high-speed vessels exhibit a wide diversity. Direct three-dimensional (3D) Computational Fluid Dynamics would be most suitable choice if not its time-consuming nature. To save computational resources and accelerate calculation speed, research works that utilize two-dimensional (2D) approaches to address problems have emerged over past few decades, which represented by strip theory plus time (2D+t) theory. Among them, Cartesian grid-based...
Abstract Objective: Utilizing propensity-score matching (PSM) to investigate the efficacy of combining glucocorticoids with Renin-Angiotensin System (RAS) blockers and Modified Huangqi Chifeng Decoction (MHCD) in treating moderate proteinuria IgA nephropathy. Methods: Patients diagnosed focal proliferative nephropathy through renal biopsy treated at outpatient clinic Xiyuan Hospital, China Academy Traditional Chinese Medicine, from October 2012 September 2022, were retrospectively analyzed....
The diffuse attenuation coefficient (Kd) is known to be closely related the light transmittance of sea ice, which plays a critical role in energy balance and biological processes upper ocean. However, commercial instruments cannot easily measure Kd ice because solid. authors this study are developing an instrument with high spectral solution irradiance profile atmosphere. Three experiments were carried out, including two in-situ Liaodong Bay one laboratory. results showed that varied depth,...
