Plug Conveying in a Horizontal Tube
Plug conveying along a horizontal tube has been investigated through simulation, using a discrete element simulation approach for the granulate particles and a pressure field approach for the gas. The result is compared with the simulation of the vertical plug conveying. The dynamics of a slug are described by porosity, velocity and force profiles. Their dependence on simulation parameters prov...
متن کاملمقدمه ای بر: تکنولوژی data base و اداره سازمان
در ادراه امور سازمان نیز از تکنولوژی data base در دو زمینه مشخص یعنی بصورت سیستم های عملیاتی و سیستم های اطلاعاتی میتوان استفاده کرد. در شرایط کنونی وجود موانع متعدد از قبیل فرهنگ غالب در سازمان های بزرگ و طرز تلقی مدیران دیوان سالار از یکطرف و تازه گی و پیچیده بودن فنون مربوط به سیتم های data base فقدان دانش، تجربه و تخصص کافی برای بهره گیری کامل از آن از طرف دیگر، برنامه ریزی و اقدام برای ایج...
15 صفحه اولConveying Location Data Using P3P.PDF
The location of an individual or a mobile terminal can be sensitive with regard to the privacy of an individual. Awarding the individual self-determination of the way position information is used will be crucial to the acceptance of the technology. This paper suggests a solution to how location data can be conveyed in privacy-friendly way using P3P combined with the PiMI method for data conveya...
متن کاملStudy on the Pressure and Temperature Distribution of Solid-Plug Conveying Element on Centrifugal Extruder
In this paper, a new polymer processing machine--centrifugal extruder is introduced. The pressure and temperature distribution of centrifugal extruder have been studied by theoretical analysis, which is based on mathematics and experiments. The results show that the pressure and temperature Distribution can provide the processing of solid-plug conveying sufficiently and stably, which can prove ...
متن کاملLocal Friction Forces between Plug and Pipe Wall in Dense Phase Pneumatic Conveying
Dense phase pneumatic conveying is widely used to transport granular materials or powder due to its efficiencies gained on cost and abrasion and erosion. To date these systems have been designed and analyzed using average frictional representation for the conveyed plug. This study explores the effect of this friction force by measuring strains on the pipe wall when the plug is moving passed the...
