The stability of supercritical Couette flow has been studied extensively, but few measurements of the velocity field of flow have been made. Particle image velocimetry (PIV) was used to measure the axial and radial velocities in a meridional plane for non-wavy and wavy Taylor–Couette flow in the annulus between a rotating inner cylinder and a fixed outer cylinder with fixed end conditions. The ...

The results from a steady, viscous flow simulation of the main flowpath of a modern jet engine transonic highpressure turbine, transition duct, and first vane of the low-pressure turbine, coupled with the secondary-air system under the high-pressure turbine, is presented. The secondary-air system configuration includes the lower cavity near the centerline, the mid-cavity with the tangential onb...

recent developments in medicine have given us a better insight into a group of disorders known as autoimmune diseases. in particular, advances have occurred in our understanding of the autoimmune inner ear disease (aied). in this article, the authors review the different postulated theories in the pathogenesis of this disease. the clinical presentation, the available para-clinical diagnostic to...
