The choice of geometrical shape of the blades has a considerable effect on aerodynamic performance and flow characteristics in axial compressors. In this paper, the effects of the blades shape on the aerodynamic design characteristics are investigated based on Streamline Curvature Method (SCM). Initially, the Streamline Curvature Method (SCM) is used for designing a two-stage axial compressor. ...

Renewable energy sources include solar, wind, hydro, geothermal and biomass. Furthermore, ocean is being rapidly harnessed worldwide. In this study, to establish a suitable design method for various bidirectional ducted tidal turbines, instead of using blade element momentum theory CFD, which have been used previously, the turbomachinery was designing turbines. A turbine optimises equipment red...

The design of a railway catenary is subject to multiple decisions regarding the geometry system. In particular, horizontal contact wire determines evolution wear and strip over time. obtained through stagger, lateral displacement at supports. value length span, curvature track, train speed within span determine which point between pantograph moves from side side. A wider stagger corresponds lar...

In recent years, the integration of Digital Twins (DT) for adoption smarter maintenance strategies has grown exponentially in different industrial sectors. New IoT and edge computing systems are being developed this purpose, however, there still some open issues challenges to be solved. Firstly, paper presents new approaches initial dependencies studied solution make a proposal improve interope...

Supersonic biplanes can achieve low-boom and low-drag supersonic flights. In the present study, aerodynamic analysis of a two-dimensional stagger Bussmann biplane (staggered upper element by 0.5c) at zero degrees angle attack with trailing edge flap was investigated help computational fluid dynamics (CFD) tools. Due to wave cancellation effect, Busemann delivers positive drag reduction design M...

The in vitro renaturation and assembly of cytokeratin molecules to form intermediate filaments (IF) illustrates that these molecules contain all of the structural information necessary for IF information. These molecules contain nine structural domains: the amino- and carboxyterminal extra helical regions, and three conserved extra helical segments that separate four helical rod-like domains. C...

In this study, the low-speed performances of Busemann biplane were clarified, focusing on relative contributions upper and lower elements to total aerodynamic characteristics biplane. Also, effects staggered biplane, which changes horizontal distance between two wings in a configuration, investigated by balance measurements numerical simulations. The flow velocity was 15 m/s, Reynolds number ba...

Strata control of ultrasoft coal seam has been a critical problem for mining and geotechnical engineers in years. In this paper, the No. 66207 longwall panel at Xinzhuangzi mine, Anhui, China, was used as an example study. A systematic approach using laboratory testing, numerical simulation, field validation implemented to investigate influences roadway layout presplit blasting on mechanical pr...
