Experimental fluid and aerodynamics focuses on measuring the physical properties and forces associated with the movement of air, water, or other fluid media. Visualization techniques, such as smoke injections, are used to show how the flow interacts with its surroundings. Results from experiments are instrumental in validating theoretical and computational models that describe any number of fluid phenomena. Common tools and equipment used to conduct experiments include wind tunnels, manometers, Venturi tubes, vortex generators, and hot-wire anemometers.

Research Interests

Design, testing and development of flow measuring instruments, such as laser Doppler, particle imaging and hot-wire anemometers; miniature pressure and temperature probes; and pressure-sensitive and temperature-sensitive paints. Flow visualization using laser induced fluorescence.

Wind tunnel design and aerodynamic testing.

Current Research Projects

Hurricane Loss Model (FDOI/FIU funded)

The objective is to develop a transparent public model to estimate residential property damage loss due to hurricanes.

Wind Effects on Emergency Rescue Vehicles (FEMA/FDCA funded)

This will determine the safest driving speeds under different wind and road conditions for fire and rescue vehicles.
