Numerical Simulation on Dilute Phase Pneumatic Transport
Pneumatic conveying is a technique that is widely used in many industrial mechanical and chemical applications. In the case of cement manufacturing pneumatic conveying is a large scale operation moving several kilograms of material per second which consumes electrical energy (operation of fans) and …

Dense-phase pneumatic transport of cohesionless solids
… a more fundamental understanding of dense-phase pneumatic transport of cohesionless solids. A 50.8 mm internal diameter circulating unit with both horizontal and vertical sections has been constructed . The pipe material is transparent lexan which allows for visual observation of the flow …

The application of laser measurement techniques to the pneumatic transport of fine particles
… of the fluid. When solid particles are conveyed pneumatically, for example in transport chemical reactors, in drag reducing flows, and in certain heat transfer processes, the particles are generally much larger than the usual seeding particles, and thus do not travel at the same velocity as the …

Pressure drop and flow characteristics for the pneumatic transport of fine particles through curved and straight circular pipes
… of the pressure drop and flow characteristics of pneumatically transported solid particles. The versatility of the test rig is demonstrated by the diversity of the investigations performed during this study. Quantitative results were acquired for the flow of different-sized alumina particles …

Epithermal neutron activation analysis of short-lived radionuclides using a pneumatic transport system and a pulsed D-T neutron generator
A pneumatic transport system for the detection and characterization of short-lived (of order 60 s or less) radionuclides produced during irradiation by a D-T neutron generator was constructed. Target samples of indium, palladium, and germanium were irradiated by the neutron generator embedded in a …

A Novel Approach To Residence Time Distribution
… systems used for power generation, gasification, pneumatic transport of material, drying, and various other tasks. An instrument was constructed for the activation, injection, and measurement of phosphorescent tracer particles in a fluidized bed riser to determine the Residence Time Distribution …

Utilization of cobalt catalyst for high temperature Fischer-Tropsch synthesis in a fluidized bed reactor
… prior to entering lean phase fluidization with pneumatic transport of the catalyst. The highest minimum fluidization velocity was found to be about 2800 sccm, there was no maximum velocity found for the reactor setup. Once characterized, the reactor was operated at pressures of 145, 217.6, and …

Pneumatic Particulate Collection System Analysis and Design
A pneumatic particulate collection system harnesses the energy associated with the release of a compressed gas to transport particulate to a collection chamber. In an effort to improve the efficiency of a previously designed collection system, high speed imaging in conjunction with computational …

NUMERICAL ANALYSIS OF TURBULENT GAS-SOLID FLOWS IN A ROUGH HORIZONTAL CHANNEL USING THE EULERIAN TWO-FLUID MODEL
… in many industrial processes including pneumatic transport of granular materials such as pulverized coal, circulating fluidized beds and dust and particle-exhaust pollution control systems. Modelling the gas-solid flow is a major challenge since the flow is turbulent which renders the …
