A Single Cylinder Engine Study Of Lean Supercharged Operation For Spark Ignition Engines, Kenneth Robert Schmid Jan 1982

A Single Cylinder Engine Study Of Lean Supercharged Operation For Spark Ignition Engines, Kenneth Robert Schmid

Masters Theses

"A comprehensive single cylinder engine test program to evaluate Lean Supercharged Operation (LSO) for spark ignition engines was conducted. The evaluation involved an experimental program studying the power, emissions, and efficiency of a single cylinder engine. The relationships between engine power, efficiency, and emissions and the engine operating variables such as absolute intake manifold pressure, Exhaust Gas Recirculation rates, and spark timing were studied"--Abstract, page ii.


Measurement Of Neck Development In Tensile Testing Using Projection Moire, Raghavan Srinivasan, C. S. Hartley, C. Raju, J. Clave Jan 1982

Measurement Of Neck Development In Tensile Testing Using Projection Moire, Raghavan Srinivasan, C. S. Hartley, C. Raju, J. Clave

Mechanical and Materials Engineering Faculty Publications

The projection moire technique affords an accurate method of measuring the geometry of the necked region in a tensile specimen. Corrections to the measured stress, necessary to account for the triaxiality introduced by the neck, require values for the radius of curvature of the specimen at the minimum section. The spacing of fringes resulting from the interference between a grating projected on the specimen surface and a master grating not only provide information which permits calculation of the radius but also demonstrates any changes in symmetry resulting from plastic deformation. Results obtained by testing specimens of copper and mild steel …

Low-Frequency Dynamics Of Moored Vessels, Bohdan W. Oppenheim, P. A. Wilson Jan 1982

Low-Frequency Dynamics Of Moored Vessels, Bohdan W. Oppenheim, P. A. Wilson

Systems Engineering Faculty Works

Three complete theories of the low-frequency dynamics of ships and disks moored with multileg mooring systems in deep water are derived, evaluated, and computerized. One theory is nonlinear; it includes the effects of cubic damping, nonlinear mooring forces and the excitation-yaw motion feedback, and it is handled by simulation. It yields random, regular and transient records, probabilities and statistics, exact and linearized transfer functions, and spectra of responses. The second theory is linear, solved in the frequency domain. The third is a static theory, which is a by-product of the linear one. Mooring lines of arbitrary compositions are considered.


High Pressure Liquid Jet Nozzle System For Enhanced Mining And Drilling, B. P. Selberg Jan 1982

High Pressure Liquid Jet Nozzle System For Enhanced Mining And Drilling, B. P. Selberg

Mechanical and Aerospace Engineering Faculty Research & Creative Works

This invention is directed to a nozzle configuration capable of enhancing the cutting and drilling effects of high pressure liquid fluid jets. The jet system is particularly adapted to configurations of two or more liquid jets which are oriented to converge at a common point. The internal nozzle configuration produces controlled instability in the jet stream causing a more rapid breakup into droplets which can be combined to produce very fast moving jets and slow moving jets when collision between droplets occur. The velocity of the fast jets so formed may be several times greater than the original velocity of …
