Mass Flow Measurement of Granular Materials in Aerial Application — Part 1 : Simulation and Modeling
The mass flow of granular particles in an aerial spreader duct was regarded as a sequence of cluster passage events. At low flow densities, the total mass per time unit could be estimated by measuring the diameter (length) of each individual particle passing a sensor and accumulating the associated masses. At higher flow densities, the lengths of clusters would be measured rather than the lengt...

The transition from frictional to lubricated flows of a dense suspension of non-Brownian particles is studied. The pertinent parameter characterizing this transition is the Leighton number Le=eta(s)gamma / sigma, the ratio of lubrication to frictional forces. Le defines a critical shear rate below which no steady flow without localization exists. In the frictional regime the shear flow is local...

testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
