Abstract

Aerofoil; NACA4412 and NACA4415 at a chord Reynolds number of 1.05×105. Firstly, the impact of the tailing edge shapes to the wake-flow behaviour is numerically investigated. Secondly, the drag coefficient is calculated and compared with the symmetric aerofoil NACA0012. The CFD RANS-SST with a commercial code ANSYS CFX simulation is performed for the fully submerged aerofoil of 150 mm chord length with three tailing edge shapes: standard straight line, saw-toothed and sine-curved shapes. The results the thicker camber, the higher drag coefficient for saw-toothed tailing edge shape. The sine-curved tailing edge provided drag results as the standard tailing edge for NACA0012 and NACA4412. The result suggests that, in term of drag consideration, it is interchangeable for using either NACA4412 or NACA4415 at this Re, as they are provided similar drag.
