the machine to be designed and developed with a view to resolve one ofthe irksome problems of this institute has been facing every year. this institute issurrounded by vast non- fertile land area of about 200 acres, which becomes widelyoccupied by numerous breads of bushes and shrubs during post-rainy season. due tothis unwanted proliferation of such verdant institute gets abysmal look and that...

A wind turbine blade's structural dynamic response is simulated and analysed with the goal of characterizing the presence and severity of a shear web disbond. Computer models of a 5 MW offshore utility-scale wind turbine were created to develop effective algorithms for detecting such damage. Through data analysis and with the use of blade measurements, a shear web disbond was quantified accordi...

In each of 2 trials, 75 female and 75 male broilers of different sizes (large and small) were obtained from a commercial grower and were commercially processed. Breast fillets were deboned at 0.25, 1.5, 3, 6, and 24 h postmortem (total n = 15 per treatment per time point). Muscle pH and L* value were determined for each deboning time. Breast fillets were subjected to texture analysis using Allo...

Purveyors are concerned about the potential food safety risk of nonintact meat products and are seeking strategies to ensure adequate meat tenderness without blade tenderization. This study was conducted to determine the effects of blade tenderization and time and temperature of aging on beef longissimus lumborum (LL) and gluteus medius (GM) tenderness. Beef strip loins (n = 300) and top sirloi...

The Freeman FT4 Powder Rheometer has been reported to describe well the powder flow behaviour in instances where other techniques fail. We use DEM to simulate the FT4 operation for slightly cohesive large glass beads at a range of strain rates. The curved impeller is shown to be beneficial in comparison to a flat blade as the variation of shear stress across the blade is reduced. The shear stre...

The effect of impeller type and shear rate on the evolution of floc size and structure during shear-induced flocculation of polystyrene particles with aluminum sulfate is investigated by image analysis. One radial flow (six-blade Rushton turbine) and two axial flow (three-blade fluid foil, four-blade 45° pitch) impeller configurations are examined. The steady state average floc size is show...

Progressive and catastrophic failure in soils has been commonly associated with the phenomenon of the shear band propagation. This paper is an attempt to validate the energy balance approach to modeling of the propagation of a two-dimensional, circular shaped shear band. This shear band can be observed in a shear blade test, performed in the novel shear-blade apparatus. The simplified analytica...

the shear strength and shear energy per unit area, as well as the force and energy required for picking flowers, are important parameters in the design and development of harvesting mechanisms. in this study, shear strength and shear energy per unit area of saffron (crocus sativus l.) stems were determined at different bevel angles and shear velocities. the force and energy required for picking...

a r t i c l e i n f o Keywords: Mixing performance DEM MGMMI Blade-rake angle Bladed mixers This study focuses on the understanding of flow over a single blade and its impact on powder mixing. The Discrete or Distinct Element Method (DEM) is used and the flow of a single blade through a bed of a binary particle mixture is studied. Mixing performance with respect to a blade-rake angle and partic...

This study involves CFD simulation of blood flow through a non-pulsatile, axial pump consisting of a complex multisectioned impeller with rotating and stationary components, and a stationary housing. We use a particlebased method, Smoothed Particle Hydrodynamics (SPH), to investigate the effects of varying the impeller blade pitch angle and the gap size between the rotor and housing. Regions of...
