Abstract:

Urban wind energy has great potential to form distributed electricity generation modules for maximizing the wind power production in a densely urbanized area. In this study developed the CFD-based evaluation procedures for determining potential mounting locations and wind power estimates with the consideration of detailed local urban topography and boundary conditions of micro-environments. The predictions including the wind velocity, direction and turbulence intensity were compared with the field measurements via ultrasonic anemometers and thermal flow velocity probes at 10 monitoring positions over five different floors inside the object building to validate the computational model as well as attain a better understanding of the interaction of the wind with buildings in complex terrain. The predicted power density and turbulence intensity profiles were further used to analyze the power density, turbulence intensity and lowest mounting height for optimizing potential mounting locations and wind power estimates. An improved roof design with rounded shape was also proposed to enhance the wind power densities with relatively lower turbulence intensities. The studied results can be useful for conducting design trades by considering the wind speed with the factors of lowest mounting height, power density, turbulence intensity and cost to optimize potential mounting sites and wind power estimates.
