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...

Thermal characterization technique for thin dielectric films

Creator:: Indermuehle, Scott W.
Abstract:: A phase sensitive measurement technique that permits the simultaneous determination of two independent thermal properties of thin dielectric films is presented. Applying the technique results in a film's thermal diffusivity and effusivity, from which the thermal conductivity and specific heat can be calculated. The technique involves measuring a specimen's front...

A computational model for resonantly coupled alpha free-piston Stirling Coolers

Creator:: Al-Hazmy, Majed Mualla H.
Abstract:: A computational model for a resonantly coupled alpha free-piston Stirling cooler is presented. The cooler consists of two isothermal working spaces for compression and expansion connected by a regenerator consisting of a stack of narrow parallel channels. The regenerator is assumed to have a linear temperature distribution along its axial...

A study of a diffusionally controlled reactive synthesis process using a multi-tube diffusion flame burner

Creator:: Snell, Douglas C.
Abstract:: A continuous process for the production of ceramic materials has been studied. This method reacted metal and oxidizer in a diffusionally controlled process, demonstrated by reacting a magnesium particle stream and hot water vapor. Many small rich hydrogen/air diffusion flames provide an atmosphere of hot water vapor, hydrogen, and nitrogen...

Frequency and phase response of a resonantly-coupled alpha Stirling cooler

Creator:: Sripakagorn, Paiboon
Abstract:: A resonantly-coupled α-Stirling (RCAS) cooler was designed and constructed. Tests on air and helium were performed with constant driving displacement over a range of frequencies. The effects of changing driving amplitude and charged pressure were studied. The use of stainless steel bellows in place of pistons eliminated the problem of...

Temperature measurement, electrical characteristics, and lorentz mixing of alkali seeded flames

Creator:: Pattee, Heidi Ann
Abstract:: When trace quantities of an alkali element are added to a flame, its optical and electrical properties change significantly. Addition of alkali seed to both premixed and diffusion flames has been used in the development of two new techniques, one for flame temperature measurement and the other for enhanced mixing....

Application of a bayesian network to integrated circuit tester diagnosis

Creator:: Mittelstadt, Daniel Richard
Abstract:: This thesis describes research to implement a Bayesian belief network based expert system to solve a real-world diagnostic problem troubleshooting integrated circuit (IC) testing machines. Several models of the IC tester diagnostic problem were developed in belief networks, and one of these models was implemented using Symbolic Probabilistic Inference (SPI)....

A numerical study of solid fuel combustion in a moving bed

Creator:: Ko, Daekwun
Abstract:: Coal continues to be burned by direct combustion in packed or moving bed in small size domestic furnaces, medium size industrial furnaces, as well as small power stations. Recent stringent restrictions on exhaust emissions call for a better understanding of the process of combustion of coal in beds. The present...
