This study used a NACA 6409 smooth wing section. Its performance is compared to an enhanced design incorporating revolving cylinder on the upper airfoil surface. The boundary conditions for present work were Reynolds (105), and attack angles (0,2,4,6,8,10,12,14,16). A turbulence model was developed (SST K-), one of aerodynamics models. well-suited sensing flow near wall. evaluated at three posi...
Mesenchymal stem cells (MSCs) and pericyte progenitors (PPs) are both perivascular cells with similar multipotential properties regardless of tissue of origin. We compared the phenotype and function of the 2 cell types derived from the same bone-marrow samples but expanded in their respective media - pericyte conditions (endothelial cell growth medium 2 [EGM-2]) for PPs and standard medium (mes...
The pupil is primarily regulated by prevailing light levels but is also modulated by perceptual and attentional factors. We measured pupil-size in typical adult humans viewing a bistable-rotating cylinder, constructed so the luminance of the front surface changes with perceived direction of rotation. In some participants, pupil diameter oscillated in phase with the ambiguous perception, more di...
This paper reports work on the two and three-dimensional numerical simulation of dough mixing with free surfaces, that arises in the food processing industry. Free surface flow in a rotating cylinder is investigated when a fluid is mixed in a cylinder with a stirrer. Different dough mixer designs are investigated. The rotating stirrer may be placed either in a concentric or eccentric arrangemen...
Water wetting is a crucial issue in carbon dioxide (CO2) corrosion of multiphase flow pipelines made from mild steel. This study demonstrates the use of a novel benchtop apparatus, a horizontal rotating cylinder, to study the effect of water wetting on CO2 corrosion of mild steel in two-phase flow. The setup is similar to a standard rotating cylinder except for its horizontal orientation and th...
Abstract. The Direct Simulation Monte-Carlo (DSMC) technique is used for numerical analysis of rarefied-gas hypersonic flows near a blunt plate, wedge, two side-by-side plates, disk, torus, and rotating cylinder. The role of various similarity parameters (Knudsen and Mach numbers, geometrical and temperature factors, specific heat ratios, and others) in aerodynamics of the probes is studied. Im...
