DEM prediction of industrial and geophysical particle flow.

Particuology 2010年第2期8卷 106-118页

作者： paul w. cleary CSIRO Mathematical and Information Sciences Private Bag 33 Clayton South 3169 Australia

Simulation of industrial particle flow. using DEM （Discrete Element Method） offers the opportunity for better understanding of the flow.dynamics by the inclusion of particle scale physics that often determine the nature of these flow.. Increased understanding from the models can lead to improvements in equip- ment design and operation, potentially leading to large increases in equipment and process efficiency, throughput and]or product quality. Industrial applications are typically large and involve complex par- ticulate behaviour in complex geometries. This paper explores the critical influence of particle shape on granular system behaviour and then discusses examples of DEM applied to several large industrial problems. 2009 Chinese Society of Particuology and Institute of Process Engineering, Chinese Academy of Sciences.

Assessing mixing characteristics of particle-mixing and granulation devices

Particuology 2008年第6期6卷 419-444页

作者： paul w. cleary Matthew.D. Sinnott CSIRO Mathematical and Information Sciences

The mixing of particulates such as pow.ers is an important process in many industries including pharmaceuticals, plastics, household products （such as detergents） and food processing. The quality of products depends on the degree of mixing of their constituent materials w.ich in turn depends on both geometric design and operating conditions. Unfortunately, due to lack of understanding of the interaction betw.en mixer geometry and the granular material, limited progress has been made in optimizing mixer design. The discrete element method （DEM） is a computational technique that allow. particle systems to be simulated and mixing to be predicted. Simulation is an effective w.y of acquiring information on the performance of different mixers that is difficult and/or expensive to obtain using traditional experimental approaches. Here w. demonstrate how.DEM can be used to unravel flow.dynamics and assess mixing in several different types of devices. These devices used for mixing and/or granulation of particulates, are classified broadly as gravity controlled, bladed and high shear. w. also explore the role of particle shape in mixing performance and use DEM to test w.ether Froude number scaling is suitable for predicting scale performance of rotating mixers.

BACKGROUND Total hip arthroplasty(THA)is a common procedure for end stage *** learning curve for THA is complex and *** of the most difficult skills to master is acetabular *** w.sh to identify if experience in arthroplasty leads to preservation of more bone *** To investigate if increasing surgeon experience w.ll predict an ever decreasing acetabular cup *** A retrospective case series of four attending orthopaedic surgeons w.s *** uncemented elective total hip arthroplasties since appointment w.re selected for *** size of acetabular cup used w.s noted and logistic regression w.s used to identify if a trend to smaller cups *** A total of 1614 subjects w.re included w.th a mean age of 64 *** cups w.re on average 0.18mm smaller per year(95%confidence interval-0.25 to-0.11,Pw.d cup sizes to decrease 0.27 mm/year for surgeon A,0.02 mm/year for surgeon B,0.15 mm/year for surgeon C and 0.29 mm/year for surgeon *** of the four surgeons had a more pronounced trend to smaller cups for male subjects than their female *** w. found increasing surgeon experience to be associated w.th an ever-decreasing acetabular cup *** acetabular cup size may act as a surrogate marker of surgical proficiency by virtue of decreased acetabular reaming.
