Item The design and validation of an impinging jet test facility.(2006-05-28T01:13:46Z) Robertson, Peter R.; Van Treuren, Kenneth W.; Mechanical Engineering.; Baylor University. Dept. of Mechanical Engineering.An experimental jet impingement facility was constructed with the capability of conducting a detailed analysis of the local heat transfer coefficients beneath an array of large impinging jets. The facility was validated with initial heat transfer studies that determined an appropriate jet discharge coefficient of 0.802 and created a correlation relating local jet Reynolds number and stagnation point heat transfer. The correlation matched closely with previous studies. The thermal effects of impinging jets were visualized by liquid crystal thermography. The resulting thermal footprints of downstream jets revealed the first known documented case of the heat transfer effects of horseshoe vortices on the target surface. This phenomenon was identified and discussed.Item An in-line microwave steam quality sensor.(2014-06-11) Faulkner, Christopher D.; Jean, B. Randall.; Electrical and Computer Engineering.; Baylor University. Dept. of Electrical and Computer Engineering.Saturated steam is a widely used industrial medium for the efficient transfer of energy. The proportion of saturated vapor steam to saturated condensate of the steam mixture is referred to as the steam quality. Accurate and reliable measurements of steam quality provides critical information for process control that effects the efficiency of energy transfer as well as protecting machine parts that come in contact with the steam mixture flow. Though many methods currently exist for measuring steam quality all have significant drawbacks in their use because of the measurement mode used. This thesis describes a microwave sensor that uses the permittivity of the steam mixture to enable an accurate and inline measurement of the quality of steam. A documented history of the theory, design, development, and testing is describe herein, with ending commentary on project potential.
