| Abstract: | This study presents pressure distribution over an
envelope of blade with and without winglets for a small wind turbine in
boundary layer wind tunnel. Different winglet configurations were tried based
on winglet height and curvature radius. Pressure measurements were made with
different chordwise and spanwise locations on the blade with and without
winglets nearby tip region. Winglet improves overall pressure difference
between pressure surface and suction surface. Presence of winglet seemed to
have the pressure increased at 0.3c and maximum pressure difference was
observed at a span of 0.95R for all winglet configurations. In suction, surface
pressure decrease was 10% for all winglet configurations. |
