Abstract

The aerodynamic characteristics of a flat plate and of a NACA airfoil with heated surface are presented in this paper. The flow field is simulated numerically by the solution of the Navier-Stokes equations. For the flat plate test case the flow is assumed steady, laminar and incompressible. The effects of grid coarsening on the solution, as well as the sensitivity of the flow field to variations of Reynolds number, Mach number, Prandtl number and surface temperature are shown. The numerical results compare well with the analytical solutions. For the NACA airfoil test case, the flow is assumed low compressible, turbulent and steady. The results indicate that maximum lift, maximum L/D and lift slope decrease with surface heating.
