DEVELOPMENT OF KRYPTON PLANAR LASER INDUCED FLUORESCENCE METHODS FOR THE MEASUREMENT OF HYPERSONIC FLOW CONDITIONS
Conventional wind tunnel flow measurement techniques typically involve the use of intrusive sensor systems, such as Pitot-probes and transducers which come in contact with the flow. Intrusive methods become impractical for high Mach number flows, as such methods can cause considerable disruption to …

The effect of dynamic operation and incoming flow on the wake of a utility-scale wind turbine
… is required. However, modeling wind turbine flows in the laboratory or in simulations is hindered by the wide range of relevant scales and the complexity of atmospheric flow and turbine operation. Because of these limitations, field scale studies are essential. Conventional field scale flow …

Rheometry and direct flow observations of a model wax-oil system
… is characterized using chemical characterization techniques, and the basic rheological properties of these components are probed using temperature sweeps and stress sweeps. Large amplitude oscillatory shear (LAOS) is also used to gain additional insight into the rheology of the model system. The …
