Abstract Cooling of the endwall a nozzle guide vane should receive special attention due to its uniqueness near-wall complex secondary flows and concomitant challenge offering film-coverage for cooling pressure-side corner regions. The use internal enhanced at backside could be an option, but it increases manufacturing cost, adds weight component, causing excessive pressure losses in air system. Novel film concepts are, therefore, required provide effective these difficult-to-cool This study...
Microchannels often serve as highways for cancer migration, and their topology largely determines the migration efficiency. Curvature, a topological parameter in biological systems, has recently been reported to be efficient guiding cell polarization migration. Curvature varies widely along curved microchannels, while its influence on remains elusive. Here, we recapitulated observed clinical tumor tissues with hydrogels, studied how cells respond curvature. We found that bend more...
The High-speed Solid-rotor Induction Motor Cooled by Natural Gas (HSIMCNG), is suitable for integrated compressors in natural gas pipeline transportation due to its high mechanical strength. In order further improve the cooling effect of motor and lighten weight, it great significance research on flow, heat transfer characteristics structure optimization. Firstly, flow state 160 kW HSIMCNG are investigated this article. Taylor vortex distribution air gap analyzed, as well obtained. Secondly,...
Reaction optimization plays an essential role in chemical research and industrial production. To explore a large reaction system, practical issue is how to reduce the heavy experimental load for finding high-yield conditions. In this paper, we present efficient machine learning tool called "RS-Coreset", where key idea take advantage of deep representation techniques guide interactive procedure representing full space. Our proposed only uses small-scale data, say 2.5% 5% instances, predict...
Squealer tip is widely used in turbines to reduce leakage loss. In typical turbine environment, the squealer flow affected by multiple factors such as relative casing motion and wide range of variable incidence angles. The development experimental methods which can accurately model real environment influencing great significance study mechanism. present paper, a low-speed cascade test facility angles (−25° 55°) built. Based on similarity criteria, high-low speed transformation method...
Abstract In this paper, detailed overall cooling effectiveness and associated flow patterns are presented for two distinct film hole distribution over a turbine endwall: an axial-row pattern iso-Mach number line row pattern. Measurements, in combination with numerical simulations, performed scaled-up cascade. Thermal protection the endwall is achieved by jet-array impingement on cold side discrete hot-gas side, combined purge air from inclined slot that simulates upstream seal cavity....
This paper analyses the main fault factors on wind turbine, and presents three general faults: gear box fault, leeway system generator fault. After analysis research of basic principle Back-Propagation Neural Network based LM arithmetic, a three-layer faults predictive diagnosis model is built. Data from two turbines are used to test effectiveness this method.
Ultra-long waves in the modified Burger model are studied by using method of travelling-wave solution. Taylor series expansion is used to isolate characteristics linear and identify nonlinear waves. The analytical solutions ultra-long with complete Coriolis force heating，which can be approximately described KdV equation combined mKdV （KdV-mKdV） equation，are obtained. cnoidal waves，solitary waves，and soliton-like also
