Effect of Gap between Airfoil and Embedded Rotating Cylinder on the Airfoil Aerodynamic Performance - Crimson Publishers
Effect of Gap between Airfoil and Embedded Rotating Cylinder on the Airfoil Aerodynamic Performance by Najdat Nashat Abdulla* in Crimson Publishers: Peer Reviewed Material Science Journals The present study explores the effect of the gap between the airfoil and the rotating cylinder embedded on leading edge of the airfoil on its aerodynamic performance theoretically and experimentally. Numerically, two-dimensional turbulent flows with Reynolds number of (700,000) based on the chord length over conventional airfoil (NACA 0012) and unconventional airfoil (NACA0012 airfoil with embedded rotating cylinder) have been investigated by solving continuity, Navier-Stokes equations and turbulent model (SST,-W) equations. The gap with (1,2,3,4 and 5 mm) between rotated cylinder and airfoil have been studied for different cylinder speed to main free velocity ratios of (Uc/Um= 1, 2, and 3) and for different angles of attack, (a), (0°, 5°, 8°, 10°, 12° and 15°). https://crimsonpublishers.com/rdms/f...
