Multi-Row Film Cooling Boundary Layers
… is to conduct several different measurements of multi-row film cooling arrays in order to better understand the physics involved with injection of coolant through multiple rows of discrete holes into a flat plate turbulent boundary layer. Adiabatic effectiveness distributions are measured for …

Investigation into the optimal cooling configuration for a gas turbine airfoil utilizing a thermal barrier coating
… configuration for a flat plate with a single row of film cooling holes and TBC. A variety of parameters were iterated upon to determine a film cooling configuration that provided a 14% improvement in overall cooling effectiveness relative to the case without film cooling while using the least …

Extended Momentum Model for Single and Multiple Hydrokinetic Turbines in Subcritical Flows
… with the Blade Element Theory in a Double Multiple Streamtube model (DMS) to predict axial loads and the performance of confined Darrieus turbines. The turbine thrust force influences the flow approaching the rotor. Hence, a momentum method is applied to solve the hydraulic transition in …

Bird Utilization of Woodland Habitat in the Eastern Quarter of South Dakota
Bird utilization of narrow, riparian woodland; riparian; block-like, tree claim; and linear, single-row windbreak habitats in the eastern quarter of South Dakota were studied during the spring migration, reproductive, and winter seasons. The relative importance of these three habitats and multi-row …
