The tip leakage vortex (TLV) cavitating flow in an axial pump was simulated based on improved shear stress transport (SST) k-ω turbulence model and the homogeneous cavitation model. generation dynamics of TLV throughout blade cascades at different numbers were investigated by numerical experimental visualizations. investigation results show that corner clearance is correlated with reversed pressure side (PS) blade, layer caused interaction between wall jet main impeller. patterns including...
Case-Based Learning (CBL) and Problem-Based (PBL) are popular methods in medical education. However, we do not fully understand how they affect the clinical thinking skills of Assistant General Practitioner (AGP) trainees. This randomised controlled trial aimed to assess effectiveness combining CBL PBL compare their impact on AGP trainees with that traditional lecture-based learning (LBL). involved 70 second-year who were randomly assigned either CBL-PBL group or LBL using a simple...
The motivation for this review paper came from the developing countries where economy is mostly dependent on agriculture and climate conditions. Based current conditions historical records, profitability in production farming depends making a right timely operational decision. Precision systematic program designed to maximize productivity of by carefully tailoring soil crop management meet specific requirements each field while preserving environmental quality. This highlights development an...
Turbulence modeling plays an important role in the accurate prediction of turbulent fluid motion computational dynamics simulations using Reynolds-averaged Navier–Stokes equations. A new one-equation Wray–Agarwal (WA) turbulence model has recently been developed by present authors to improve nonequilibrium flows with large separation and curvature. In this paper, WA is employed simulate internal flow characteristics a U-bend, computed results are compared experimental data. The obtained from...
Sewage pumps are widely utilized in various applications, including municipal wastewater treatment plants, industrial processes, and residential sewage systems. These specifically designed to handle the transportation of mixtures consisting solid liquid components, commonly observed as two-phase flow. In this study, semi-open with varying clearance sizes have been examined through adjustment geometrical model. Multi-factor analysis variance is employed investigate combined influence...
TiO2-based dye-sensitization cycle is one of the basic strategies for development solar energy applications. Although power conversion efficiency (PCE) dye-sensitized devices has been improved through constant attempts, intrinsically fatal factor that leads to complete failure PCE TiO2-mediated not yet determined. Here, by using isotopically labeled MAS-1H NMR, ATR-FTIR spectroscopy (separate H/D and 48Ti/49Ti experiments), ESR, we revealed accumulative formation Ti-H species on TiO2 surface...
The end clearance of the impeller is one most important structural parameters in hydraulic design a high-speed electrical submersible pump (ESP). In this paper, an ESP with rotating speed 6000 r/min was taken as research object. Numerical calculations were carried out for five different conditions 0.1 mm, 0.3 0.6 0.9 and 1.2 respectively, to obtain performance internal flow field under situation. simulation results verified by experiment. It showed that increase led decrease head efficiency...
Fluidized bed is the main reactor for heating and gasification of coal, biomass, other solid fuels. The diameter, density, shape particles significantly affects gas–solid two-phase flow process. Based on numerical method combining computational fluid dynamics discrete element (CFD–DEM), this paper mainly performs simulation gas–solid process coarse under different inlet mass rates with diameters 2.5 mm, 3.0 3.5 respectively. high-speed photographic experiments were carried out to validate...
Abstract Sewage pumps are one of the most popular types fluid machinery in municipal, industrial, and environmental engineering many other fields. The influence tip clearance size on pump performance internal flow field distribution within a sewage was investigated this study based numerical calculation test verification. Three models with different clearances were obtained by adjusting assembly structure simulated computational dynamics software to solve Navier–Stokes equations for...
ZnO arrester plays an important role in protection of transit overvoltage to power equipment. The degradation is inevitable as the equipment operated for a long period time. Water-induced one most common causes failure. sensitive leakage current monitor tendency water-induced relatively low. To improve monitoring method, mesoscopic characteristics and mechanisms need be investigated. In this paper, experiments arresters re conducted using three types with different kinds glazes. grain...
