Numerical Studies on Teeter Bed Separator for Particle Separation

Five-Zone Simulating Moving Bed for Ternary Separation

Five-zone Simulating Moving Bed (SMB) system, designed for ternary separation, is a modified form of standard four-zone SMB which is only effective in binary separation. It was reported in literature that the five-zone SMB separates the extract-II stream with a lower purity value than that of raffinate and extract-I streams. To address this issue, five zone SMB was designed, using safety ma...

Rival Penalized Competitive Learning Based Separator on Binary Sources Separation

This paper 1 presents an approach named Rival Penalized Competitive Learning based Binary Source Separator (RPCL-BSS), which has two major advantages: (1) fast in implementation , (2) able to automatically determine the number of binary sources, and (3) able to reduce the noise eeects. Experiments have shown that RPCL-BSS algorithm can not only nd out the correct number of sources quickly, but ...

Numerical Studies of the Cahn-Hilliard Equation for Phase Separation

Numerical Simulation on Flow Field of Oilfield Three-Phase Separator

The conventional measurement method can no longer guarantee the accuracy requirement after the oilfield development entering high water cut stage, due to the water content and gas phase in the flow. In order to overcome the impact of measurement deviation the oilfield productionmanagement, the flow field of three-phase separator is studied numerically in this paper using Fluent 6.3.26. Taking i...

Experimental and numerical infiltration studies in a wadi stream bed

Moisture content data from an infiltration experiment undertaken in the dry main stream bed of wadi Habawnah, south-west Saudi Arabia, are reported. A simple experiment enabled hydraulic properties of the multi-layer soil profile to be inferred through inversion of an unsaturated soil water simulation model. The results indicate a heterogeneous but highly transmissive profile and suggest that s...
