Abstract

With the growing environmental concerns of international aviation carbon emissions are driven by the ever-increasing commercial aviation traffic. This study aims to increase the aerodynamic efficiency of the NACA 0012, by implementing cavity vortex generators with the intent to increase the effective stall angle without a substantial increase of drag. This study is performed with Reynolds Averaged Navier-Stokes (RANS) at a low Reynolds of 5.0E+04 with varying cavity depths along the leading edge. The depths study is placed at 10 percent cord at depths of 3, 5, and 10 percent cord. All cavity vortex generators effectively increased the stall angle by 4 degrees, increasing the aerodynamic performance and aircraft safety. The 5 percent cavity depth resulted in the highest reduction in drag while maintaining the benefits of the 3 and 10 percent depths. Ice accretion modeling was performed for commercial high Reynolds applications to assert no negative impact on the generated ice shape weight. The flight conditions replicate the flight in known icing conditions during ascent, with an elevation of 8000 feet, Mach 0.4, and temperature of 272.35 K. The results conclude an increase in the overall ice weight in Kg for all cavity vortex generators except 10 percent depth with a reduction of 4.49 percent.
