Site visits of advantages for both the students and companies involved, were typically undertaken in the third year of the four-year including: bachelor degree in conjunction with the Engineering Third year students have the chance to visit a company they Manufacturing module. Due to the increasingly high number of might be considering for their work experience ahead of the students that are enrolled in the module, a huge strain had been final year of their course. This gives students the opportunity placed on the participating companies, with a great deal of staff of strengthening their engagement with that particular input and resources being required, without any direct benefit in company, or makes them more aware of the operations of the return. This led to a decline in the number of companies willing company. This will result in both students and companies to participate and in 2004 the program was cancelled. being more satisfied about their work experience placement.

Staff Profile – Professor Colin Hansen Professor Colin Hansen has been Head of the School of and Sir Keith Smith Fund; the Australian Research Council Mechanical Engineering since 1996 and an Academic Staff (ARC); the University of Adelaide; the Australian Electricity member at The University of Adelaide since 1986. Prior to 1986, Supply Industry Research Board (AESIRB); Australian Mineral he worked as a Consulting Engineer for seven years, including Industries Research Association (AMIRA); Dept. of State four years as a Senior Consultant in noise and vibration Development; Ford (Aust); Bruel and Kjaer (Aust.); Dept of engineering with Bolt, Beranek and Newman Inc. in Los Industry, Technology and Commerce (DITAC); National Angeles, USA. Professor Hansen has spent his entire Teaching Company Scheme; DSTO-AMRL; Dairy Research and professional life consulting, researching and teaching acoustics Development Corporation; SA Water; and the US Air Force and the control of noise and Office of Scientific Research. vibration. For the last fifteen He has published 10 books, 8 chapters in edited books and years, his focus has been on numerous technical papers in international journals and active noise control and more conference proceedings. He has supervised over 20 PhD recently on ultrasonics for students and many honours projects and he is keenly interested water treatment. Funding in the supervision of industry sponsored student projects bodies and corporations involving any aspect of design or noise and vibration control. which have supported his research over the past 17 Professor Hansen can be contacted on 8303 5698 or email years include: the Sir Ross firstname.lastname@example.org to discuss possible projects. Professor Colin Hansen Chilling Sounds By Dr. Carl Howard conditioning system compared to a conventional vapour- compression system are: 1. It has no moving parts (except for the fan), and hence is extremely reliable. 2. The working fluid is either air or helium. Both of which are benign to the environment, have zero global warming potential, are non-corrosive, and hence are environmentally friendly. 3. It can be powered from the waste heat generated by an engine, which improves a vehicle’s fuel efficiency and reduces Pictures of the thermoacoustic refrigeration device built at the University of greenhouse gas emissions.

The School of Mechanical Engineering is conducting research Researchers in the School of Mechanical Engineering have into the use of sound to create an air-conditioner which is constructed a device, shown in the figure across, which uses powered by the waste heat from a car's exhaust. high amplitude sound waves to create a 15ºC temperature Thermoacoustics, as its name implies, uses sound to create a difference across two heat exchangers. The device uses air as temperature difference, or vice versa: a temperature difference the working fluid and hence it is environmentally benign. This creates high amplitude sound waves. The technology was device uses a standard audio loudspeaker to create the high developed over 20 years ago and is slowly gaining acceptance amplitude in sound waves. Future work will involve replacing the as a viable commercial technology with companies such as loudspeaker with a thermoacoustic device that generates high Unilever and Praxair investing in this technology.

Prof Hacker and Dr. Schneider both are seasoned pilots. Potential activities of the new centre include: microgravity flight experiments – using the aircraft in free-fall to create a near zero-gravity environment for a few seconds, simulating conditions in space; a “flying wind tunnel” – instead of using laboratory-based wind tunnels, attaching instrumentation and models to the aircraft and flying them through real-life turbulence conditions; alternative-powered aircraft – investigating ways of flying aircraft with as little fuel as possible, or no fuel at all. “We will have a strong student base, which means we will be Photo by James Knowler, courtesy of the Independent Weekly. able to get a lot of student involvement in research projects,” Dr Schneider said. The universities of Adelaide and Flinders have joined forces to Dr Schneider said students in the University of Adelaide’s create the Centre for Aeronautical Research and Education Aerospace Engineering degree would directly benefit from the (CARE). Based at Parafield Airport, the new centre brings experience of working with CARE. “In addition to the benefits for together the combined strengths of the two universities in undergraduate students, the funding we have received will also aerospace engineering and atmospheric science. Dr Gerald support a postgraduate scholarship,” he said. Schneider co-heads the new CARE centre with Associate CARE has been established with funding from the Sir Keith & Professor Jorg Hacker.
