In both cases, strains are measured directly on specimens using a novel laser-based interferometric technique. Young's modulus and Poisson's ratio as well as the entire stress-strain curve can be measured. The quality and resolution of these simulated images are outstanding, and direct matching between simulated images and experimental observations is now possible. The Corrsin Wind Tunnel is named after the late Hopkins professor Stanley Corrsin, who designed and built this facility to study fundamentals of turbulent flow. For additional information, browse the home page for the Turbulence Research Group Hydrodynamics Laboratory Facilities for research in hydrodynamics include a pump test facility designed for acoustic and quantitative flow visualization experiments, a high speed jet cavitation facility that includes a vortex ring generator, and a second high speed jet for turbulence measurements.
Equipment associated with jet cutting technology is also available.
In addition, a holographic system is also being assembled for in situ measurements in the ocean. Close ties with the David Taylor Model Basin provides access to towing tank facilities for quantitative visualization of large scale wakes and separated flows. For additional information, browse the home page for the Laboratory for Experimental Fluid Dynamics Heat Transfer Laboratory Equipped with wind tunnels for heat transfer measurements, this laboratory is devoted to the study of heat transfer in complex geometries in single phase and two phase flows. A model of a thermoacoustic refrigerator helps researchers visualize unsteady temperature distributions and flow fields during the device's operation. PC - based data acquisition systems and a digital image processing system with software developed for this purpose are used for data acquisition and quantitative analyses of visualization images obtained by holographic interferometry, thermocromatic liquid crystals, or infrared photography.
