15 صفحه اولNumerical Simulation of Particle Separation in the Fluid Flow in a Microchannel Including Spiral and Acoustic Regions
Particulate separation has many applications in medicine, biology and industry. In this research, the separation of polystyrene particles with a diameter of 10, 20 and 30 μm in the fluid flow of a microchannel is investigated. The microchannel consists of a spiral region and a straight region under the influence of acoustic waves. In the spiral region, the particles under hydrodynamic effects u...
متن کاملThe Structural Properties of Isolated Galaxies, Spiral-Spiral Pairs, and Mergers: The Robustness of Galaxy Morphology During Secular Evolution
We present a structural analysis of nearby galaxies in spiral-spiral pairs in opticalBV RI bands and compare with the structures of isolated spiral galaxies and galaxies in ongoing mergers. We use these comparisons to determine how galaxy structure changes during galaxy interactions and mergers. We analyze light concentration (C), asymmetry (A), and clumpiness (S) parameters, and use the projec...
متن کاملThe Integrated Polarization of Spiral Galaxy Disks
We present integrated polarization properties of nearby spiral galaxies at 4.8 GHz, and models for the integrated polarization of spiral galaxy disks as a function of inclination. Spiral galaxies in our sample have observed integrated fractional polarization in the range . 1% to 17.6%. At inclinations less than 50 degrees, the fractional polarization depends mostly on the ratio of random to reg...
متن کاملGalaxy 0421 +040p06: an Active Spiral (?) Galaxy with Extended
The infrared bright galaxy 0421 +040P06 detected by IRAS at 25 and 60 μm has been studied at optical, infrared, and radio wavelengths. It is a luminous galaxy with apparent spiral structure emitting 4 x 1037 W (1 x 1011 L 0 ) from far-infrared to optical wavelengths, assuming H 0 = 75 km s1 Mpc1• Optical spectroscopy reveals a Seyfert 2 emission-line spectrum, making 0421 +040P06 the first acti...
