A comparison of a rigid (top) and flexible (bottom) airfoil in heaving motion, showing kinematic pressure (p). Note how the morphing of the flexible airfoil has introduced camber into the blade profile, reducing the angle of attack and vortex size, resulting in an 80% increase of propulsive efficiency in this particular case.
Air phase volume fraction (top) and air phase velocity profile of a Venturi aspirator. Such devices can be used to oxygenate wastewater and increase efficiency in aquaculture settings
Temperature profile of a sensible (concrete) heat energy storage system. Such systems can be used in concentrated solar power (CSP) applications, and allow for solar energy to be stored during the day, so that electricity can be produced at night.
Temperature contours, in K, for banks of tubes used to recover low-grade waste heat from industrial exhaust. Images (a) and (b) represent higher and lower flow velocities, respectively. Both (a) and (b) compare a well-insulated (top) case with poorly insulated (bottom) case. The spacing and size of these recovery tubes can be optimized to minimize blower input energy by monitoring pressure drop.
