Computational fluid dynamics was used to search for the links between the observed pattern of attack seen in a bauxite refinery’s heat exchanger headers and the hydrodynamics inside the header. Validation of the computational fluid dynamics results was done by comparing then with flow parameters measured in a 1:5 scale model of the first pass header in the laboratory. Computational fluid dynami...

The diffuser total efficiency was formulated and defined based on the generalized actuator disc model for index of diffuser-alone diffuser-augmented wind turbines. An optimization method to maximize developed using a genetic algorithm axisymmetric computational fluid dynamics. A case study conducted 10% chord-to-diameter ratio, 2% thickness-to-chord plate, crest position at 50% chord diffuser. ...

Solving the hydroelastic problem by using Ansys System Coupling (Mechanical and CFX) for floating fixed rings of a deformable annular seal made it possible to analyze influence cylindrical shell thickness, inlet outlet edge dimensions, pressure, shaft radial displacement on hydrostatic pressure distribution clearance value length, leakages, stress-strain state, force. The analysis static stabil...

The flow field in a centrifugal fan is highly complex with flow reversal taking place on the suction side of impeller and diffuser vanes. Generally performance of the centrifugal fan could be enhanced by judiciously introducing splitter vanes so as to improve the diffusion process. An extensive numerical whole field analysis on the effect of splitter vanes placed in discrete regions of suspecte...

Liquid Natural Gas (LNG) processing facilities typically are located on ocean shores for easy transport of LNG by marine vessels. These plants use large quantities of water for various process streams. The combined wastewater effluents from the LNG plants are discharged to the coastal and marine environments typically through submarine outfalls. Proper disposal of effluents from an LNG plant is...

An advanced light-fidelity (Li-Fi) system based on the blue Gallium nitride (GaN) laser diode (LD) with a compact white-light phosphorous diffuser is demonstrated for fusing the indoor white-lighting and visible light communication (VLC). The phosphorous diffuser adhered blue GaN LD broadens luminescent spectrum and diverges beam spot to provide ample functionality including the completeness of...

A previous paper [Applied Acoustics 66, pp.709-730, 2005] has shown that adding a quadratic residue diffuser (QRD) to the top of a T-shape barrier can provide better barrier performance than an equivalent purely absorptive barrier. In here, we extend the study to look at the performance when a QRD is made absorptive. This paper presents an investigation on the acoustic performance of a few well...

In the Russian Federation, 80% of agricultural land is in unstable moisture. The economic crisis at end last century affected state reclamation hydraulic structures. large-scale reconstruction and construction systems planned until 2030 requires development new media for them. use renewable energy sources to control water supply heart injection flow controllers. structure an alternative automat...

During non-generation periods, leakage through the wicket gates of a hydroturbine often results in very poor quality water (low or zero dissolved oxygen) in the tailrace of the hydropower facility. Generally, the leakage rate is relatively small, usually about 5-10 cfs per turbine. A bottom-mounted diffuser system was designed based on laboratory-measured and manufacturer-supplied specification...
