Abstract:

STOL aircraft use a variety of mechanisms to augment lift. Small fans with vectored exhaust imbedded in an aircraft wing could increase lift and reduce drag. The aim of this thesis is to investigate the two-dimensional effect of a small fan in wing on the flow field and on the lift and drag behavior of a NACA 0012 airfoil. Numerical solutions are obtained for a Mach number of 0.3 and a Reynolds number of one million. The parameters examined are angle of attack, fan ejection angle and suction velocity. The numerical code used is based on the Beam-Warming implicit factorization algorithm for solving the two- dimensional mass-averaged compressible Navier-Stokes equations for viscous, unsteady flows. Keywords Drag reduction, Lift augmentation, Computational fluid dynamics, Mass transfer, Vectored blowing, Theses.
