Investigation on the Separation Performance of a Multicyclone Separator for Natural Gas Purification

This study evaluated the separation efficiency and developed a pressure drop model for a multicyclone separator used for natural gas purification. The collection and grade efficiencies of a multicyclone separator with 15 single cyclone separators were evaluated at inlet velocities of 6–24 m/s and particle concentrations of 30–2000 mg/m at atmospheric pressure and room temperature. The experimen...

Magnetic Structure of Actinide Metals

In comparison to 3d or 4 f metals, magnetism in actinides remains poorly understood due to experimental complications and the exotic behavior of the 5 f states. In particular, plutonium metal is most especially vexing. Over the last five decades theories proposed the presence of either ordered or disordered local moments at low temperatures. However, experiments such as magnetic susceptibility,...

Enhancement of Gas-filled Microbubble Magnetic Susceptibility by Iron Oxide Nanoparticles

INTRODUCTION Gas-filled microbubbles were originally developed as an intravascular contrast agent to enhance backscattering in ultrasound imaging. Microbubbles possess the ability to be an MR susceptibility contrast agent due to the induction of large local magnetic susceptibility differences by the gas-liquid interface. Feasibility of microbubbles as an MR pressure sensor, based on the suscept...

Numerical Study of Gas-solid Flow in a Cyclone Separator

This paper presents a numerical study of the gas-powder flow in a typical Lapple cyclone. The gas flow is obtained by the use of the Reynolds stress model. The resulting pressure and flow fields are verified by comparison with the measured results and then used in the determination of powder flow that is simulated by the use of a Stochastic Lagrangian model. The separation efficiency and trajec...
