Catastrophic propagation of ductile cracks in metallic foils

Creator:: Elliott, Leonard Thomas
Abstract:: The sudden failure of metal structures under load, which has been a design problem for many years, is characterized by a crack propagation rate which approaches the speed of sound in the material. These failures, which are often known as catastrophic fractures, may be divided into two types which depend...

A numerical analysis of ice fog produced by automobiles

Creator:: Nelson, William George
Abstract:: A model of an exhaust plume was developed and programmed on a digital computer. The purpose of the model was to predict the concentration and size distribution of ice particles produced from automobile exhaust during arctic conditions. The model accounted for the nucleation, growth, and freezing of the condensed water...

Condensation of a zeotropic mixture, R-454C, and its individual components, R-1234yf and R-32, in microfin tubes

Creator:: Matty, Ethan P.
Abstract:: This work compares the condensation heat transfer and pressure drop for zeotropic refrigerant R-454C and its individual components, R-32 and R-1234yf, in horizontal microfin tubes. One microfin tube has a 4 mm outer diameter, 0.18 mm wall thickness, and a surface area ratio of 1.56. The second tube has a...

A computer imaging method for fluid motion studies in metal casting

Creator:: Poland, John H.
Abstract:: 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...

Using Digital Human Modeling to Evaluate and Improve Car Pillar Design: A Proof of Concept and Design of Experiments

Creator:: Mellon, Taylor R. P.
Abstract:: Considering human factors in early engineering design stages can improve expensive late stage processes, facilitate user safety, improve product quality and help reduce the need for physical prototyping. Currently, car pillar design (the vertical pillars between windows which connect the roof and car body) provide safety for the passengers in...

Effect of lateral force on passenger comfort during a mechanically assisteddependent transfer

Creator:: Mast, Jonathan J.
Abstract:: Air travel presents several problems for passengers with disabilities. One in particular is how they get from their wheelchair and to an aircraft seat. The commonly used manual transfer method is hazardous to the assistants and the passenger. There are other alternatives, but they have plenty of room for improvement....

Integrated forward light scattering as a measure of aerosol mass concentration

Creator:: Tomine, Chris Shinya
Abstract:: A mathematical model was developed that relates the ratio, R, of two light flux measurements to the mass concentration, m, of the atmospheric aerosol particles between a source of parallel light (e.g., the sun) and the measuring system. R is defined as the ratio of the light fluxes passing through...

Modeling hop kilning with respect to energy consumption and drying kinetics

Creator:: Thomas, Matthew W.
Abstract:: Currently, little work has been performed studying energy consumption in hop kilning. This thesis explores drying with an alternative drying schedule that extends the initially elevated drying temperature currently used by growers and examines its impact on drying time and energy use. Extending the time of the initially elevated drying...
