Abstract

In this study, the effect of Heat Transfers on lift and drag coefficients of two symmetric and camber airfoils with plunging motion in laminar flow is numerically investigated. The compressible Navier– Stokes equations are discretized using a Finite Volume method and they are solved by PIMPLE algorithm. In this simulation, fluid dynamic viscosity and thermal conductivity are considered to be variable. Also Dynamic Mesh method is used for oscillating motion. The results show that, by reducing the airfoil surface temperature less than the free flow temperature, lift to drag ratio increases. Moreover, influence of Heat Transfer on vortexes pattern at airfoils trailing edge and therefore its impact on the aerodynamic coefficients are investigated.
