We tested the aerodynamic function of nasal conchae in birds using CT data from an adult male wild turkey (Meleagris gallopavo) to construct 3D models of its nasal passage. A series of digital "turbinectomies" were performed on these models and computational fluid dynamic analyses were performed to simulate resting inspiration. Models with turbinates removed were compared to the original, unmod...

Innate hearing processes define the realism that can be obtained from reproduced sound. An unspecified system with two loudspeakers in a room places considerable limitations upon the degree of auditory realism that can be obtained. It has been observed that loudspeakers and room must be hidden from the auditory scene that is evoked in the listener’s brain. Requirements upon the polar response a...

The integrating sphere is used in photometry to h.measure total luminous flux. In a sphere with a diffusely reflecting coating, the illuminance by reflected > light is approximately the same at all points on the sphere surface and is proportional to the total flux emitted by the lamp. This reflected light is measured at a point on the sphere surface which is shielded from the direct rays of the...

free surface sloshing of liquid in a rectangular tank induced by lateral excitation has been studied numericallyand experimentally in this paper. the numerical simulation is carried out based on the volume of fluid (vof) method that provides free surface extraction in such problem. a tank with transparent walls is used to free surface tracking in experimental study while the movement amplitude ...

The computational fluid dynamics (CFD) technology is analyzed and calculated utilizing the turbulence model multiphase flow to explore performance of internal circulating fluidized beds (ICFB) based on CFD. three-dimensional simulation method can study hydrodynamic properties ICFB, bed optimized. fluidization ICFB improved through experimental cross-shaped baffle. Then, baffle funnel-shaped pla...

A single–phase flow model was used to analyze the uniformity of field in desulfurization tower under different baffle combinations, and a multiphase explain gas solid two–phase characteristics chemical reaction tower. The stability behavior solids one furnace two towers discussed. results show that installation shielding plates at appropriate positions for sulfur removal is beneficial enhance u...

introduction patients with palliated congenital heart disease may present later in life for major, non-cardiac surgical procedures. although alternative surgical techniques are now available for the treatment of the transposition of the great arteries (tga), an atrial level baffle (mustard or senning procedure) was previously performed. long-term adverse effects of the atrial level switch inclu...

In this article, mixed convection heat transfer of alumina-water nanofluid in an inclined and baffled C-shape enclosure is studied. It is assumed that the flow is laminar and steady. There is no energy production, energy storage and viscous heat dissipation. Furthermore, the nanofluid is considered as a continuous, Newtonian and incompressible fluid. Governing equations are discretized by finit...
