ABSTRACT: The objective of this research is mainly focused on environment-friendly
and moderately slow flapping wind turbine which can easily operate in or near
urban areas or rooftops owing to scale merit with low-frequency turbine noise,
installation cost, avian mortality rate and safety consideration etc. We
considered lift and drag based slow flapping type wind turbine to operate in
the residential arena. In order to study the flapping wind turbine performance,
we collect ten years of wind velocity records from the Bangladesh
Meteorological Department for two different stations in Bangladesh. The
velocity contours and profiles have been the points of observation to find out
the suitable turbine shape having the efficiency to initiate the turbine
rotation. We made a simple comparative study of the wind velocities profile
obtained from the different stations in Bangladesh. A simple numerical study
has been conducted and presented by graphical analysis to inspect the wind flow
above the constructed structure. Finally, we analyze the wind velocity for the
individual months and determine the turbine performance in terms of torque for
the average wind velocities of Dhaka and Cox’s Bazar stations.
