Thermal Control of an Electronic Enclosure Utilizing a Vapor Chamber
Title
Thermal Control of an Electronic Enclosure Utilizing a Vapor Chamber.
Creator
Dougherty, Michael L., Evans, Ronald D., Engineering
Abstract / Description
Florida Technological University College of Engineering Thesis; This thesis addresses the problem of stracting heat from sealed electronic enclosures. Typical industry practice is to use various air-to-air and air-to-liquid heat exchangers. These techniques are known to require costly custom designs. This thesis points out how one can apply heat pipe technology in the form of a vapor chamber to solve this type of problem. The details on the design and testing of two prototype vapor chambers...

Typical industry practice is to use various air-to-air and air-to-liquid heat exchangers. These techniques are known to require costly custom designs. This thesis points out how one can apply heat pipe technology in the form of a vapor chamber to solve this type of problem. The details on the design and testing of two prototype vapor chambers are cited. Included in the text are typical industrial applications that required sealed enclosures to protect their associated electronic control hardware. Also mentioned is some historical background on heat pipes.

Analytical and experimental investigation of pumped solar hot water systems
Title
Analytical and experimental investigation of pumped solar hot water systems.
Creator
Pearce, Jeffrey B., Evans, Ronald D., Engineering
Abstract / Description
Florida Technological University College of Engineering Thesis; A transient computer model of a forced circulation solar hot water system has been developed. The model allows for capacitance effects by solving the energy balances on a four node model of the solar collector. The tank model is designed to include the presence of an auxiliary heater and to allow for the non ideal condition of load drawoff. Five tests were done to validate the computer model. These tests include a comparison of...

The model allows for capacitance effects by solving the energy balances on a four node model of the solar collector. The tank model is designed to include the presence of an auxiliary heater and to allow for the non ideal condition of load drawoff. Five tests were done to validate the computer model. These tests include a comparison of the computer simulation with experimental data and a model available in the literature. The results of these tests indicate that the computer model is able to predict the collector inlet and outlet temperatures within 10% for typical operating conditions.

Nose Tip Recession Measuring System for Hypersonic Test Vehicles
Title
Nose Tip Recession Measuring System for Hypersonic Test Vehicles.
Creator
Brown, James Anthony, Evans, Ronald D., Engineering
Abstract / Description
Florida Technological University College of Engineering Thesis; A method is presented which permits the measure of nose tip recession of re-entry vehicles and advanced terminal interceptors by employing a double choked flow coolant gas system. Recession of the tip results in an increased exit flow area which reduces the total pressure of the gas in the blast tube. Measurement of the blast tube pressure and gas generator (chamber) pressure will produce an effective measurement of the nose tip...
Show moreFlorida Technological University College of Engineering Thesis; A method is presented which permits the measure of nose tip recession of re-entry vehicles and advanced terminal interceptors by employing a double choked flow coolant gas system. Recession of the tip results in an increased exit flow area which reduces the total pressure of the gas in the blast tube. Measurement of the blast tube pressure and gas generator (chamber) pressure will produce an effective measurement of the nose tip recession as long as choked flow (i.e., sonic velocity) is maintained in both the tip exit area and the gas' generator throat area. Governing flow equations documented in the literature are developed for double choked flow. Hypersonic wind tunnel test data are presented to verify the developed flow equations and to identify the mass flow ratios necessary to sustain double choked flow.
