Research Interests:

Dr. Hugo came to the department in July of 1999 after spending four years as a research scientist with the US Air Force Research Lab in Albuquerque, NM where he performed basic and applied research in support of the Airborne Laser program. Dr. Hugo's research interests involve the development of high-temporal bandwidth optical-wavefront measurement systems and their application to non-intrusive flow interrogation. Of current interest is the flow of an axisymmetric jet exhausting into either a quiescent or a cross-flow environment, and the application of both passive and active flow control methodologies to enhance the mixing process under varying external conditions. These flows are of industrial concern in applications such as process burners, process heaters, incinerators, jet-engine combustion and exhaust, and flare-stack burners.

Non-intrusive optical wavefront measures of the Shack-Hartmann variety provide a means of understanding the spatial development of the jet's evolving vortical structure at high-temporal bandwidth. These measurements, coupled with more traditional measurement techniques involving micro-thermocouple temperature probes, hot-wire anemometers, and gas sampling probes are used to assess, understand, and improve the methods of jet-flow control. The resulting benefits of such research are improved combustion efficiency in the case of energy release, improved destruction efficiency in the case of incineration, and a reduction in acoustical emissions in the case of engine exhaust.

Current Research Interests:

• Optical-wavefront measurement hardware development
• Axisymmetric-jet flow control, passive and active techniques.
