Turning the Cylinder
These poems were written between September 1989 and July 1993. They represent four years of work in university workshops, one-on-one and group sessions with local writers, and long hours spent on my own. As influence, I acknowledge every poet I've ever read and admired, from Shakespeare to Sharon …

Lift on a rotating cylinder
… was primarily to find whether lift on a rotating cylinder in an air stream increases with increase in roughness of cylinder. All previous experiments on the subject (within the knowledge of the writer and subject to the limitation of the references entered at the end of this report( limited …

Electro-magnetic control of cylinder wake
… for manipulating wake flows past a solid cylinder in an electrically low-conducting fluid (e.g. seawater). The intent is to avoid both vortex shedding and flow separation from the body. It is desired to reduce the mean drag significantly and prevent the lift from becoming non-zero at all …

Preliminary design of twin-cylinder engines
… deals with the preliminary design of a twin-cylinder engine. The goal of the work is not to make the detailed design of the engine but to draw the main characteristics of each kind of engine and to investigate which configuration of twin-cylinder engine matches in the best way to given …

Flow Between a Cylinder and a Rotating Coaxial Cylinder, Axisymmetric Shaft With Axially-Periodic Radius Variation, or Screw
"Flow between a circular cylinder and an inner shaft driven by an axial pressure gradient or boundary rotation is considered computationally. In spiral Poiseuille flow (SPF), where the inner shaft is a circular cylinder, complete linear stability boundaries are determined for a wide range of …

Heat Transfer In Tightly Packed Cylinder Arrays
… an internal channel. In most applications, the cylinders have a spacing of over 2 diameters (2D) between their center points in both the lateral and downstream directions. One option for battery thermal management in hybrid/electric aviation is to use cylindrical batteries packed in arrays with …

Oblique shock interactions with gas cylinder interfaces
This thesis presents an experimental study of fluid instabilities formed due to an oblique interatction of a shock wave with a cylindrical gas column seeded with glycol droplets. Two gases are injected into quiescent air to form the column. The first is sulfur hexafluoride (SF6) which generates the …

Bore polishing of diesel engine cylinder liners
… been identified by the examination of Tornado cylinder bores from an engine test. The graphite structure is visible on the surface which has a surface finish of less then 0.125 micro-m in C.L.A. value. The components used in these tests were a grey cast iron piston ring running on a grey cast …

Input impedance of a slot-cylinder antenna
… analysis is made of the input impedance to a cylinder antenna with an axial slot. It is excited by a parallel-wire line connected across the center of the slot. This causes standing waves along the slot. The analysis is then based on an analogy between the slot and a transmission line. …

The tangential drag of an axially oscillating cylinder
… of the tangentiaì drag of an axially oscillating cylinder is presented. Deep-sea mooring cables are oscillated sinusoidally at ocean wave amplitudes and frequencies, and experimenta1 values of the tangential (friction) drag coefficient are obtained. The experimental values of the drag coefficient …

Planar shock wave interaction with a multiphase cylinder
We present an experimental study that visualizes the effects of a planar shock front passing through air (or SF6) randomly seeded with glycol droplets or smoke particles. It was observed, using a high-speed multiple-CCD (charge coupled device) camera, that an instability occurs as the shock wave …

Planar Graphs and their Duals on Cylinder Surfaces
… drawings of undirected and directed graphs on cylinder surfaces. In the case of undirected graphs, the vertices are positioned on a line that is parallel to the cylinder’s axis and the edge curves must not intersect this line. We show that a plane drawing is possible if and only if the graph is …
