Abstract

CFD simulations of a triangular airfoil in low-Reynolds-number compressible flow are performed using the commercial CFD software ANSYS Fluent. This airfoil is one of the candidates for propeller blades on a possible future Martian air vehicle design. The goal of this paper is to study the aerodynamssics and flow physics of a triangular airfoil at angles of attack (AOA) from 0 to 14 deg. at Mach number of 0.15 and 0.5. Reynold-Averaged Navier-Stokes (RANS) equations with a number of turbulence models, namely the SA, SST k-ω, and recently developed Wray – Agarwal (WA) model are solved. The computations are compared with the experimental data to assess the accuracy of various turbulence models. It is shown that SST k-ω and WA model give the most accurate result.
