Full-Water Column Turbulence Parameterization Of Stratified Waters In Southern Lake Michigan, Kyla A. Prendergast, Cary D. Troy, David Cannon
Full-Water Column Turbulence Parameterization Of Stratified Waters In Southern Lake Michigan, Kyla A. Prendergast, Cary D. Troy, David Cannon
The Summer Undergraduate Research Fellowship (SURF) Symposium
Full water column mean flow and turbulence structure was characterized at two stratified locations in Lake Michigan (a. Muskegon, MI; b. Michigan City, IN) in order to better understand the filtration potential of invasive quagga mussels. Invasive quagga mussels in Lake Michigan are filter feeders and can dramatically alter clarity as well as the biological/chemical characteristics of the water column. This filtering capacity is highly contingent on turbulence characteristics throughout the water column, which is poorly understood in the Great Lakes. Using velocity, temperature, and turbulence data collected from these locations, the structure of the water column turbulence was modeled …

Assessing The Hydraulics Of Water Heaters By Adding Fluoride As A Tracer To Inform Its Overall Effect On Water Quality, Christian A. Guerrero, William Schmidt, Antoine Aubeneau, Amisha D. Shah
The Summer Undergraduate Research Fellowship (SURF) Symposium
As residential water heaters are the primary source of waterborne disease outbreaks in the U.S. there is a need to better understand how they are contributing to decreased water quality in buildings. Previous work has indicated that intermittent stagnation, low disinfection residual and operation temperatures promote the growth of pathogens in water heaters. The overall effect of hydrodynamics of water heaters on these factors remains unclear. Therefore, a tracer study was performed to determine the effect of and characterize hydraulics of the typical residential water heater on water quality. Controlling temperature and flow rate, a pilot-scale hot water system (50 …

Laboratory Characterization Of Unsteady Boundary Layers, Umair Sarwar, Cary Troy
The Summer Undergraduate Research Fellowship (SURF) Symposium
The study of waves and their effects on mean flow and turbulence in natural water bodies is an important issue for applications in aquatic biology, coastal engineering, sediment transport and hydrodynamic of the lake. These waves result in the generation of an oscillatory (Stokes) boundary layer near the bottom of the water column. The goal of this study was to conduct various experiments that will be used to characterize the turbulence in unsteady boundary layers and help understand the relation between various flow variables (e.g. wave amplitude, frequency, water depth, turbulent kinetic energy, etc.). Using the research facilities provided, three …
