The capabilities of the Tektronix Model J2C/7J20 Rapid Scanning
Spectrometer for the determination of molecular species resulting from
Otto cycle combustion were experimentally investigated after a literature
search of the subject area. Combustion of hydrogen-air, carbon monoxideair,
and gasoline-air mixtures in the combustion chamber of a Cooperative
Fuel Research engine...
The flow configurations around and the forces acting on a
circular cylinder with its axis parallel to a nearby plane boundary
and subjected to a uniform flow were investigated. The flow conditions,
which were perpendicular to the cylinder axis and parallel to
the plane boundary were investigated experimentally and theoretically....
Hydrodynamic forces on a cylinder oscillating horizontally
underwater with its axis perpendicular to the motion
were measured at the Oregon State University Wave Research
Facility. The cylinder had an outer diameter of 12 inches
and a length of 12 feet. For the data presented herein, the
maximum displacement of the...
Significant reductions in the number of defects in parts
produced by investment casting can be obtained by improving
the flow of the molten metal during pouring. Studies have
been done at Oregon State University with simulated casting
techniques to determine optimal mold configurations.
Better mold layouts have been shown to...
The problem of determining whether a crack impinging on an interface will penetrate into the substrate or deflect along the interface is vital to the effective design of layered and composite material systems. Of particular interest is the transition between crack propagation by penetration through an interface and deflection along...
The ability to engineer stiffness and strength in any desired direction make composites an ideal material candidate for various applications when compared to their traditional isotropic counterparts. In spite of this, the ability to model the material response in composites has yet to be fully explored. Composite research largely focuses...
Prototyping is a crucial step in product design and development, but it is also known as the highest sunk cost. The top 20 Research and Development (R&D) department spends 142 billion dollars, yet 40 to 46 percent of this money goes into developing products that cannot even make to the...
Mechanical behavior of Nb-Ti superconducting composites with copper matrices have
been studied experimentally and theoretically.
Experimental work includes extensive measurements of Cu/Nb-Ti composite system.
Techniques for fine fiber testing and composite wire measurement have been developed.
Experimental parameters examined in this research include geometry, hardness, Young's
modulus, Poisson's ratio, yield...
