Spatial Variation of Drag on Long Cylinders in Sheared Flow

A method is described for measuring the local drag coefficient on a long cylinder which exhibits vortex-induced vibration (VIV). Results are shown from a field experiment in which a long flexible pipe was instrumented with two-hundred and eighty fiber optic strain gauges. The measured local drag coefficients are compared to a commonly used drag coefficient prediction formula. The formula is sho...

Hydrodynamic stability of flow between rotating porous cylinders with radial and axial flow

A linear stability analysis was carried out for axial flow between a rotating porous inner cylinder and a concentric, stationary, porous outer cylinder when radial flow is present for several radius ratios. The radial Reynolds number, based on the radial velocity at the inner cylinder and the inner radius, was varied from 215 to 15, and the axial Reynolds number based on the mean axial velocity...

Magnetohydrodynamic Flow in Horizontal Concentric Cylinders

This article presents the exact solutions of the velocity and temperature fields for a steady fully developed magnetohydrodynamic flow of a viscous incompressible and electrically conducting fluid between two horizontal concentric cylinders. Our study focuses on the influence of the Hartmann number, Brinkman number, Péclet number and inner radius on the fluid temperature field, entropy generati...

Axial Particle Diffusion in Rotating Cylinders

We study the interface dynamics of a binary particle mixture in a rotating cylinder numerically. By considering only the particle motion in axial direction, it is shown that the initial dynamics can be well described by a one-dimensional diffusion process. This allows us to calculate a macroscopic diffusion constant and we study its dependence on the inter-particle friction coefficient, the rot...

Systemic right ventricle supported by implantable axial-flow assist device.

In 30-year-old man with a history of Mustard correction of transposition of the great arteries (TGA), HeartMate II (Thoratec Corporation, Pleasanton, CA, USA) assist device was implanted into the failing systemic right ventricle. The shape and size of the device were designed for left ventricle insertion. This requires special attention to verify the correct position of the inflow cannula and p...
