Simulation of the Effect of Centrifugation on Membrane Efficiency by Using Computational Fluid Dynamics During the Clarification of Pomegranate Juice
Background and Objectives: Pomegranate juice is prone to turbidity, which makes it hard to preserve and concentrate. Microfiltration is one of the membrane processes that can be used to reduce its turbidity, but, it is prone to membrane fouling. Pretreatment is considered the most effective way to reduce membrane fouling. Materials and Methods: This study simulated the effect of centrifugation...
متن کاملComputational Fluid Dynamics Simulation of Structured Packing
An electronic representation of Sulzer’s Mellapak N250Y structured packing was generated by subjecting a physical packing element to CT scan. The resulting file was imported into a three-dimensional imaging program and then copied, translated, and rotated to create a stack of three packing elements. This stack was then inserted into an open-ended cylindrical surface to approximate a packed colu...
متن کاملReservoir simulation-based modeling for characterizing longwall methane emissions and gob gas venthole production
Longwall mining alters the fluid-flow-related reservoir properties of the rocks overlying and underlying an extracted panel due to fracturing and relaxation of the strata. These mining-related disturbances create new pressure depletion zones and new flow paths for gas migration and may cause unexpected or uncontrolled migration ofgas into the underground workplace. One common technique to contr...
متن کاملMultiphase flow and tromp curve simulation of dense medium cyclones using Computational Fluid Dynamics
Dense Medium Cyclone is a high capacity device that is widely used in coal preparation. It is simple in design but the swirling turbulent flow, the presence of medium and coal with different density and size fraction and the presence of the air-core make the flow pattern in DMCs complex. In this article the flow pattern simulation of DMC is performed with computational fluid dynamics and Fluent...
متن کاملSimulation of Cumuliform Clouds Based on Computational Fluid Dynamics
Simulation of natural phenomena is one of the important research fields in computer graphics. In particular, clouds play an important role in creating images of outdoor scenes. Fluid simulation is effective in creating realistic clouds because clouds are the visualization of atmospheric fluid. In this paper, we propose a simulation technique, based on a numerical solution of the partial differe...
