AbstractThe current study reports on the results of two-dimensional Navier-Stokes simulations of an NACA0006 airfoil and force measurements interacting with either an airfoil-wake or a cylinder-wake under the low Reynolds number condition. The configuration of the airfoil-wake is constructed based on a design of Mars airplane unit No.2. The diameter of the cylinder in the configuration of the cylinder-wake is determined by a thickness of the main airfoil of the Mars airplane. The chord-based Reynolds number is 14,000. The angle of attack varies -4 degrees to 10 degrees. The computed aerodynamic coefficients in the airfoil-wake and without the wake interaction cases are in reasonable agreement with the experimental data when the angle of attack is less than 6 degrees. The results show that the lift coefficient and lift curve slope of the NACA0006 reduce due to the wake interaction. The characteristics of the wake depend on the relative configuration and the size and shape of the main object and play an important role in resultant aerodynamics of the horizontal stabilizer of the Mars airplane.
