A Study on Performance Investigation, Simulation and Testing of Vertical Axis Wind Turbine with Omni- Directional Duct for Tall Building in Urban Location

In this paper an efficient design for enhancing the performance of the ducted wind turbine (DWT)
mounted in the tall buildings is presented. The DWT generates differential pressures and also causes
mass flow through a building integrated turbine. By the help of Catia V5 software a successful design
was completed for building mounted duct wind turbine and also computational fluid dynamics (CFD)
modeling of optimum design with an octahedral casing was chosen. A comparative study is done with
the results of CFD analysis and actual wind turbine. By this innovative design cost of the tower is
completely reduced and also omnidirectional intake helps in capturing wind with the seasonal
direction. During the wind pressure the flow within augmented openings which subsequently
accelerates, expands and releases into the environment. The process involves capture, acceleration
and concentration of wind into the turbine. The increased kinetic energy will drive the permanent
magnet generator.
