Current Research Project(s):

The research efforts of Dr. Paul Walsh are focused on applied aerodynamics related to high-speed air intakes for propulsion, wing performance and contamination on commercial aircraft, and power generation using ducted flow wind turbines. The work on high-speed air intakes looks at the problem of starting such systems using controlled mass extraction via bleed hole dynamics. The holes are modelled numerically and configured to provide the appropriate mass bleed in the presence of real gas effects. The wing performance study investigates the contamination of internal wing cavities due to airborne particulates. The objective is to reduce particulate residuals and subsequent corrosion using judicious internal design. The objective of the ducted wind turbine research is to develop the potential for enhanced power generation using fluid structure interactions. Dr. Walsh welcomes inquiries regarding his work from interested researchers and potential industrial collaborators.
