A theoretical and experimental study is performed of rapid, fully developed flows of cohesionless granular materials down inclined chutes with a rough base. Two flow types are studied in detail: (1) immature sliding flow, where a stagnant zone forms on the base of the chute, and (2) fully developed sliding flow, where no such zone is formed. A simple phenomenological theory is developed that pr...

Stepped chute flows are characterized by intense turbulence and strong flow aeration, but most studies did not investigate the turbulence characteristics. In this study, highly turbulent air-water flows skimming down a large-size stepped chute were systematically investigated. An experimental study of detailed air-water flow properties measurements were introduced in different types of flow reg...

A series of laboratory experiments and numerical simulations have been performed to investigate the rapid fluid-like flow of a finite mass of granular material down a chute with partial lateral confinement. The chute consists of a section inclined at 40◦ to the horizontal, which is connected to a plane run-out zone by a smooth transition. The flow is confined on the inclined section by a shallo...

For example, the feedrate and accuracy of a weighbatching system’s conveyor or feeder doesn’t exclusively determine the system’s overall capacity and accuracy. Other factors that may affect productivity and success include material delivery method, infeed rate, surge vessel capacity, weighing equipment location in relation to mixers, hopper and chute design based on the material’s physical prop...

The relationship between working chute temperament and beef carcass quality traits were measured on 183 crossbred feedlot steers. Steers were weighed and sorted into 16 pens and weighed every 28 days. Temperament was evaluated as exit velocity (EV), chute score (CS), and catch score (CAPS). Tissue samples were collected for DNA profile including docility (IGENITY®, Merial Limited, Duluth, GA, U...

Relationships between behavioral and physiological symptoms of preslaughter stress and LM Warner-Bratzler shear force (WBSF) were investigated using Bos taurus steers (n = 79) and heifers (n = 77). Measurements of heart rate, respiration rate, rectal temperature, and concentrations of serum cortisol and plasma epinephrine were used as indicators of stress associated with physical handling and c...

In this work, the signals generated by grain-to-base multiple impacts of three different granular materials flowing along an inclined chute and characterized unsteady-state conditions are investigated through discrete element method (DEM). The effect grain-size angularity grains taken into account. Various instants flows studied, focusing in particular on analysis signal produced passage materi...

Stepped chute flows are characterised by intense turbulence and strong flow aeration (Fig. 1), but most studies did not investigate the turbulence characteristics. Detailed air-water flow properties were measured in skimming flow on a stepped chute (θ = 16o, h = 0.05 m). Longitudinal oscillations of depth-averaged flow properties were observed with a wave length of about two step cavity lengths...
