Local convective heat transfer coefficients were measured on a two-diameter long cylinder in axial flows of air at conditions unexplored so far, by using thermochromic liquid crystals (TLC) coated on an electrically heated strip-foil consisting bonded to the external surfaces. The Reynolds numbers (Re) based on the cylinder diameter were between 8.9 · 10 and 6.17 · 10, and the flow in front of ...

In 1992, I was hired by the State of Oregon as an expert witness in a trial of four chiropractors who had been accused of using a "Toftness-like device" in their practices. The "Toftness Radiation Detector" was an appliance designed by a chiropractor for diagnosing ailments. It consisted of a metal cylinder shaped somewhat like a thick soup can. At one end was a lens; at the other was a smooth ...

The flow interception efficiency, which provides a measure of the fraction of streamlines that intercept a porous collector, is an important parameter in applications such as particle capture, filtration, and sedimentation. In this work, flow permeation through a porous circular cylinder located symmetrically between two impermeable parallel plates is investigated numerically under different fl...

The flow-induced transverse vibration of a cylinder (diameter [Formula: see text]) with an attached flexible and elastic plate high aspect ratio to its leeward side is investigated numerically at low Reynolds number 150 for range reduced velocities ( U r ) using in-house developed fluid solver based on curvilinear immersed boundary method strongly coupled open-source finite element-based struct...

A numerical study of steady-state, fully developed, MHD duct flows is presented for the case of an applied transverse magnetic field and a two-dimensional variation of the flow parameters in the plane perpendicular to the flow direction, with no variations in fluid properties. Solutions are found for (i) rectangular ducts with no obstacles and (ii) rectangular ducts containing thin flat plates,...

This report discusses the energy balance results observed during the simulation of the impact of an aluminum sphere on an aluminum plate supported by a hollow aluminum cylinder. Due to the high impact velocity, there is considerable ringing of the cylinder which causes the sum of the mechanical energies to increase. An optimal set of input parameters is identified that minimizes ringing and red...

The numerical simulation of the three-dimensional flow upwind of a vertical cylinder over a flat plate is achieved with a parallel LES code which is called DNSUTA Version III. The preliminary computational results with a coarse grid find that the flow structure is similar to experimental observations. The bow shock is very clear, and a separation shock is formed ( Λ -structure). Inside the sepa...

The transverse flow-induced vibration (FIV) of an elastically-supported cylinder-plate assembly (viz., a rigid splitter-plate attached to the downstream side circular cylinder) with low mass ratio 10 and zero structural damping is investigated using numerical simulations at Reynolds number 100. oscillations characteristics flow around structure are analyzed in terms fluid forces as function pla...

A new antibiotic, aterrimin (Lewis et al., 1953), is unstable in aqueous solution at pH 7, and insoluble at lower pH levels. Aterrimin can be dissolved in absolute alcohol and the solutions can be used satisfactorily in a cylinder-plate type of assay (Heatley, 1944). Further investigation has established that sevbral other organic solvents are nontoxic to various bacteria when used in cylinders...
