Airborne sampling of particles emitted to the atmosphere from Kraft paper mill processes and their characterization by electron microscopy

Creator:: Augustine, Frank Edward
Abstract:: A high volume sampling system, employing Nuclepore filters and designed for sampling particulate in the plumes from industrial sources using a light aircraft, is described. The effluent of kraft paper mills was sampled using this system and then analyzed by electron microscopy. Size distributions of particles were obtained at several...

An experimental study on the use of inclusion trapping devices for investment casting

Creator:: Buckingham, Ronald W.
Abstract:: A problem facing the casting industry is inclusions in the finished parts. The inclusions can be sand from the molds, oxides or other impurities in the metal charge. Inclusions lead to costly part repairing or reworking. A study was done to try and find inclusion trapping devices that could be...

Comparing Delay and Reflected Inertia for an Actuated Spring Loaded Inverted Pendulum Model

Creator:: Reinschmidt, Kurt W.
Abstract:: Legged robots, while advancing quickly, have far to go before they can recover from major disturbances safely and consistently. Reflected inertia, which affects how quickly the actuators can physically respond to an environmental disturbance, and delay, which describes the time necessary for the controller to sense, re-plan, and respond to...

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...

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...

Sampling submicrometer particles suspended in near sonic and supersonic free jets of air

Creator:: Martone, Joseph Arthur
Abstract:: This experiment is concerned with sampling submicrometer particles in near sonic and supersonic flows. The study employed a high volume condensation aerosol generator to produce stearic acid particles having a geometric mean diameter of 0.8 μm and a geometric standard deviation of 1.28. The aerosol was diluted with dry air...

Evaluation of the predictive capability of two-phase flow maps for microchannel condensation of R-134a at low mass flux conditions

Creator:: VanderPutten, Michael A.
Abstract:: Predicting condensation flow regimes and the associated heat transfer and pressure drop in microchannels is critical for designing terrestrial and space systems for heating, cooling, power generation, and advanced manufacturing. It is well established that in flows approaching the microscale (Dh < 1 mm) gravity-dominated flow regimes become less relevant,...
