von Karman Vortex Street

A vorticity contour plot of a flow past an obstruction (Re = 120) that displays the phenomenon referred to as the von Karman vortex street (St = 0.16).

Non-Newtonian Fluids

This is a combination of corn starch and water. The combination is a non-Newtonian fluid, which means that the viscosity can change under shear stress changes. This material, sometimes called Oobeck after a Dr. Seuss book, Bartholomew and the Oobleck, is an equal volume of dry, powdered corn starch and water (tap water is fine).

Upper Mutale River Basin Hydromet Station

Data are critical in water resources management.  Researchers from Duquesne University and the University of Venda conducted river discharge measurements and installed a weather station at a local school.  The weather station will provide, among other parameters, precipitation data, which will be used to model the watershed.    The river discharge measurements will be used to measure the amount of surface water that flows through the valley.  Students from Duquesne and Univen are also planning to deliver modules at the local primary school on weather and climate.  The river discharge measurements will be used to model the watershed and hopefully construct a method to determine surface water quantity from satellite images.  Satellites allow researchers and resource managers to quantify the river water in the past where river gage measurements do not exist.

NSF Research Experience for Undergraduates

Search for research projects specifically designed for undergraduates funded by the National Science Foundation (NSF). The NSF provides grants for research projects where undergraduate students participate supervised by faculty or a graduate student. Undergraduates can apply for programs at different schools; the researchers for each of the programs choose who will join. Students must be U.S. Citizens, Nationals, or permanent residents.
