Steady vortex ows past a circular cylinder are obtained numerically as solutions of the partial di erential equation = f( ). We illustrate several classes of solutions.

Unsteady flow past a circular cylinder at a Reynolds number of 300 has been simulated. The spanwise extent of the computational domain has been systematically varied from zero (2-D) to a large value of 12&, where 4 is the spanwise wavelength of the fundamental mode-B 3-D instability (Williamson, 1996). Simulations with intermediate spanwise extent of 4 and U, have also been performed so as to i...

Subjects experienced an illusion of self-motion when viewing the randomly patterned inner surface of a cylinder rotating about their main body axis. This sensation of rotation in a direction opposite to the direction of cylinder rotation is known as circular vection. An experiment was conducted to ascertain if the production of circular vection involved a binocular process in the visual system....

The original protocol for implant prosthesis recommends the use of a gold framework for acrylic and ceramic prosthesis. However, due to its high cost, the use of alternative alloys is desired. This study compares the marginal accuracy of pre-made cylinders versus plastic cylinders cast with two different base metal casting alloys. Five samples each of (1) plastic cylinder cast in cobalt-chromiu...

This work reports on experiments that were performed with a freely vibrating cylinder exposed to currents and placed near a plane boundary parallel to the cylinder axis. It is observed that the proximity of the boundary affects the vertical response of the cylinder in two ways: (i) for gaps between 0.75 and 2 diameters (D), the amplitude of oscillation is reduced; (ii) for gaps smaller than 0.7...

2014 Using a simple continuum model for a paramagnetic fluid we analyze a simple shearing flow and parallel flow through a pipe. We also examine the possibility of maintaining a steady circular flow in a circular cylinder by rotating a homogeneous magnetic field.

Natural convection in an annulus with a discrete heat source on the inner cylinder is studied numerically. The outer cylinder is isothermally cooled at a fixed low temperature, and the top wall, the bottom wall and unheated portions of the inner cylinder are thermally insulated. For low applied heat flux through the heater, as measured non-dimensionally by a Grashof number, Gr , the flow in the...
