The effects of the gap ratio and angle of attack of side-by-side twin wind blades. Seven characteristic smoke-streak flow patterns were defined. The vortex-shedding frequency decreased as α increased. The maximum lift occurs at α = 10° and drag increased with α. The flow on the upper wind blade were similar to those of single wind blade.
