CHATTANOOGA ENGINEERS CLUB http://www.utc.edu/~engrcs/cec/cec.htm Volume LI April 3, 2000 12:00 noon Number 12 The Cellar at Union Square THIS WEEK__________________________________________________________________ Joe Kilpatrick will speak on two separate "end-use" projects that are sponsored by TVA's Public Power Institute: * Frostless Heat Pump Development * Home Automation. The Frostless Heat Pump Development presentation will discuss a new patent technology that is being tested by TVA and Oak Ridge National Labs. The technology will improve the performance and comfort level of an air-source heat pump. This technology was among the top 100 of the 1999 R&D Magazine award winners. The Home Automation presentation will give an industry overview and discuss some of the things electric utilities are doing to help bring this technology into your home. Monthly Program Chair: Mike Ingram. Thanks to IEEE and PPI for providing several informative programs. LAST WEEK___________________________________________________________________ Brian Taylor and Josh Green, graduating mechanical engineering students from UTC Senior Design class presented on the tack/paving project sponsored by Roadtec. As part of their senior interdisciplinary design course, a team of 11 engineering students is working on this real-world project. The project requires that the team evaluate the feasibility of mounting an asphalt bonding agent (tack) distribution system directly on existing asphalt paving equipment, thereby, eliminating the need for a separate truck for tack distribution. The current paving train consist of milling machine, tack distribution, asphalt truck, shuttle buggy, and the paver. Students studied a design from France, Vogelle, as well as research on patent infringement, before proposing a design. The UTC design is to attach the existing sprayer to the paver. The design concern is to be able to perform the tack distribution at the slow speed of the paver. Some of the initial testing were done by spraying water at the slow speed. At 400 degree, tack has the similar property of water. The project will not be completed by this group of graduating seniors, testing is planned for this semester, another group can continue the project. Based on the results of these tests and engineering analyses performed by the team, students from this semester will present to Roadtec the loss coefficient, required pump pressure for the nozzle, as well as the spray pattern. The final analysis will be presented at the end of April.
