Understanding the roles that various microbes play in silage fermentation and the factors that affect their growth can help us understand why silages ferment in various ways. In many, but not all cases, the fermentation that a crop undergoes can be explained by how microbes interact with factors such as moisture content, buffering capacity, and sugar content. However, management factors such as...

The paper describes results of FE-simulations of confined granular flow in silos with and without inserts. The numerical analysis was performed with the help of an uncoupled Arbitrary Lagrangian-Eulerian (ALE) approach. The behaviour of the granular material was described with a non-local hypoplastic model. The FEresults of silo flow were compared with experiments in a large-scale silo. Both th...

Grain stored in silos the United States of America is generally cooled with an aeration system to limit mold spoilage and insect infestation. Monitoring efficacy real-time conditions grain done using temperature cables fixed-spaced sensor locations that are hung from roof silo. Numerous placement options exist terms number their positions. However, little investigation has been into effects cab...

We propose a simple model for arch formation in silos. We show that small pertubations (such as the thermal expansion of the beads) may lead to giant stress fluctuations on the bottom plate of the silo. The relative amplitude ∆ of these fluctuations are found to be power-law distributed, as ∆−τ , τ ≃ 1.0. These fluctuations are related to large scale ‘static avalanches’, which correspond to lon...

Abstract: With the increasing volume demand of silos, squat silo diameters are bigger and bigger. However, present wall pressure computation methods are mostly based on small diameter silos. To solve this problem, systematical research on the wall pressure in squat silos is of great importance. For now, in the Chinese code the wall pressure computation methods are based on the limit equilibrium...

The main factors that influence the quality of the raw meal during its production in a ball mill and storage in stock and homogenisation silos of continuous flow are investigated. A detailed simulation is used, incorporating all the key characteristics of the processes. The quality modules of the raw meal are controlled via robust PID controllers, optimized with the same simulator. The effect o...

The influence of eccentric discharge of stored solids in squat silos has been highly valued by many researchers. However, calculation method of lateral pressure under eccentric flowing still needs to be deeply studied. In particular, the lateral pressure distribution on vertical wall could not be accurately recognized mainly because of its asymmetry. In order to build mechanical model of latera...

Techniques for nonparametric regression based on fitting small-scale local models at prediction time have long been studied in statistics and pattern recognition, but have received less attention in modern large-scale machine learning applications. In practice, such methods are generally applied to lowdimensional problems, but may falter with high-dimensional predictors if they use a Euclidean ...

The silo discharge process is studied by molecular dynamics simulations. The development of the velocity profile and the probability density function for the displacements in the horizontal and vertical axis are obtained. The PDFs obtained at the beginning of the discharge reveal non-Gaussian statistics and superdiffusive behaviors. When the stationary flow is developed, the PDFs at shorter tem...
