Download or read book Application of coupled CFD DEM simulation to separation process in combine harvester cleaning devices written by Christian Korn and published by Springer Nature. This book was released on 2020-06-01 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the application of the coupled CFD-DEM approach for simulating the separation of grain and material other than grain in combine harvester cleaning devices. Based on a literature study, it describes the most important influencing factors and presents a database for particle parameterization. It investigates the separation process in two steps with differing levels of process abstraction. The first step involves numerical separation in a vertically oscillating box with airflow, and in the context of a sensitivity study, investigates the effect of selected material, contact and operating parameters on the target variables’ separation time and grain purity. In the second step, the numerical separation process was performed in a 200 mm wide segment of a combine harvester cleaning device. The numerical results were then compared with experimental investigations in order to confirm the method’s applicability.

Download or read book Rheological Properties of Granular Materials written by Alisa Victoria Vasilenko and published by . This book was released on 2011 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: Granular materials can be found at any stage of processing in many industries, such as food, pharmaceuticals, catalysts, and chemicals. These materials exhibit a variety of flow patterns, and their state and behavior differ from application to application. Since there is a lack of fundamental understanding of particulate or powder behavior, multiple problems can be encountered during routine manufacturing. Scale-up can also be a challenge, as the lack of constitutive equations for granular materials forces most scale-up efforts to follow the trial-and-error route. Powder characterization measurements are employed as both a selection tool and a predictive method for the material's process performance. Therefore, it plays a very important role in process and product development. The numerous existing methods used to characterize the flow properties of powders are mostly application-specific and it is not clear how they correlate with each other or with process performance. Moreover, understanding the relationships between the material properties and the processing conditions is necessary for a successful design of a continuous manufacturing system, which has been a major focus for pharmaceutical industry in the recent years. Before such changes can be implemented, a better understanding of fundamental physical phenomena governing powder flow behavior must be developed. In this work we study particulate/powder flow behavior experimentally using several characterization methods, including the Gravitational Displacement Rheometer (an avalanching tester), the rotational shear cell, and the compressibility tester. We establish the variables of interest through correlative comparison and study the differences and similarities between the methods in order to investigate particulate/powder flow behavior during processing and characterization. A mixing rule for principal stresses is developed through investigation of shear behavior of binary mixtures in a shear cell. In order to better understand the mixing rule the relationship between the particle-particle contact density and measured stresses in a powder bed is explored with DEM simulations. Powder testing methodologies were applied to a case study where the efficiency of the catalyst dry impregnation process was analyzed. As a result, predictive rules and characterization guidelines were developed for different powder systems subjected to various processing conditions.
Download or read book Mechanical Properties of Granular Materials Using Nanoindentation and Modeling with Distinct Element Method written by Amal Kumar Dutta and published by . This book was released on 2006 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: The mechanics of granular material is an important issue that governs many geotechnical engineering applications. Two types of particles having similar particle size, but different shape are used in this research to evaluate the role of particle morphology on the physical properties of its assemblage. Experimentation of 1-D compression behavior at constant axial strain rate under laterally confined conditions is performed for these two particulate materials and the behavior of the stress path is analyzed in relation to the initial material packing and physical characteristics of the granules. The behavior of granular assemblages under imposed loading conditions are also evaluated by analyzing the macro and micro level morphological changes (in terms of shape and size distribution) resulting from 1-D compression tests. Various experimental procedures and techniques are employed for characterizing the size and shape aspect of these particles. The mechanical properties (hardness, modulus, and time dependent creep parameters) of the individual particles are determined and analyzed using nanoindentation technique. Nanoindentation has emerged recently as a powerful tool for precise measurements of mechanical properties of materials. Considering its potential applicability in the broad area of micromechanics associated with granular materials, an in-depth study of its application is performed. Since a rigorous study of the nanoindentation technique for finite size particles has not been done to date, initial testing for developing appropriate experimental and interpretation procedures required testing reference material such as fused quartz and novel composite materials to gain additional insight and experience. For this reason, besides granular materials, the changes in mechanical properties for structured materials (blended single wall carbon nanotube-epoxy composite specimens) are also included in this research. The micromechanical analysis of granular assembly using computer simulation through the program PFC2 [superscript D] (2-Dimensional Particle Flow Code), an application of Distinct Element Method (DEM) is also performed. The material micro-properties such as particle shear stiffness and normal stiffness values are assigned from the nanoindentation test results for the two granular materials. The particle contact behavior, nature of force chain structure, and uniformity of deformation associated with 1-D compression on granular materials having different shape and mechanical properties are analyzed.
