Advisor Martin Wosnik Graduate Co-Advisor Kyle Charmanski Characterize blade design/turbine performance in free stream in student wind tunnel (and validate in FPF) Investigate power output vs. turbine array spacing in FPF turbulent boundary layer A potentiometer was used to vary loads on the model wind turbines to characterize the power output. Pitot-static tubes were used to measure average wind speed at hub height. The custom-designed force balance was used to measure thrust (drag) on turbine rotor. Wind Turbine Array Test Plan: 1x1, 2x1, 3x1, …, 6x1: vary S x in diameter increments 3x3 array: vary both S x and S x in diameter increments Research Methodology Offshore Wind Turbine Array Scaling of 1:500, D=25 cm diameter rotor Turbine performance = f ( c P, c T, ) Design Tip Speed Ratio:  =  D/2U = 3.5 Hub height H = 0.75 D Blades designed using 1D Blade Element Momentum (BEM) Theory Blades modeled within SolidWorks, and rapid-prototyped in ABS plastic. 3 different designs were tested. 1 turbine mounted on force balance 8 turbines rigidly mounted to base plate Model Wind Turbine DesignResultsConclusions Unites States has target to produce 20% of electricity from wind energy by 2030 (at 2.9% in 2011) Many very large wind farms will be installed, including offshore wind turbine arrays. Millions of dollars are lost each year due to inefficient array spacings. The University of New Hampshire's Flow Physics Facility (FPF) is capable of producing high Reynolds number turbulent boundary layers comparable to the earth’s atmospheric boundary layer (FPF test section dimensions: width 6.0 m, height 2.7 m, length 72 m) The objective of this study was to design realistic, scaled offshore wind turbines, and investigate the effects of wind turbine array spacing on wind farm power output. Background and Motivation Figure 5: Power coefficient vs. tip speed ratio for selected turbine design (mod 3). Figure 8: Turbine placed in free stream velocity with varying loads to characterize the performance of the blades. Figure 9: Turbine placed in turbulent boundary layer with varying loads to characterize the performance of the blades. Figure 10: 6x1 array while varying spacing from 6 to 12 diameters as shown to the right. All turbines given same load with front at a TSR=4.5 Determine distance to fully recover boundary layer velocity profile behind leading turbine. Study 3x3 array varying S x and S y Further Studies Figure 11: (1xN) array spacing experiments in FPF(shown here S x = 6D). (bottom left) turbine collecting data in turbulent boundary layer. Figure 1: (above) Diagram showing velocity deficit caused by upstream turbines. Figure 2: (right) Horns Rev offshore wind farm located in the north sea off of the shore of Denmark Wind turbines are able to operate at higher power coefficient in free stream (uniform flow) vs. in boundary layer (shear flow) Velocity deficit produced by first row turbine causes a significant reduction in power for downstream turbines Increasing turbine spacing improves overall array power output Real world installations of wind farms cannot have turbines spaced too far apart, turbine spacing based on cost-benefit analysis (increased earnings from larger Sx vs. increased cost, e.g., from land/ocean lease and connection cost/power cables). This study can provide engineering input for cost-benefit analysis Figure 6: (below left) model turbine with force balance set up for testing in FPF (shown at downstream location x=61m,  ~ 1m).
