Research Interests

Primary Research Theme: Vibrations and Fluid-Structure Interaction
Research Group/Lab : Fluid Structure 1

My principal research interests are in fluid-structure interactions, flow-induced vibrations, aero- and hydroelasticity, dynamics, nonlinear dynamics and chaos. This research is related to and is of interest to the power-generating industry, offshore mechanics, and the aeronautical industry; but other components of the research are longer-term fundamental investigations, with no immediate industrial motivation. In terms of practical applications, this research is related to heat exchangers, aircraft engines, risers in the oil and gas industry, nuclear reactors, valves, piping, acoustic streamers and towed underwater vehicles, solution mining and ocean mining applications, the respiratory and haemodynamic systems, and so on.

Current Research Projects

• Towed systems for gas and oil exploration
• Piping systems for ocean mining and production of liquid nitrogen at sea
• Vibrations in heat exchangers and nuclear reactor internals
• Flutter of plates and electricity generation
• Low-damping devices for MEMS/nano applications
• Modeling of pressure pulsations and wall vibrations in hydraulic lines
• Piping vibration in solution-mined salt caverns
