摘要: Abstract Heat transfer characteristics and flow structure in turbulent flaws through a flat plate three-dimensional boundary layer containing built-in vortex generators have been analyzed by means of the space marching Crank-Nicolson finite difference method. The method solves “slender” approximation steady Navier-Stokes energy equations. This study used eddy diffusivity model standard k-e to predict heat field with imbedded longitudinal vortex. results show distortion due vortices, such as strong spanwise divergence thinning. skin friction relatively good comparison experimental data. core moves slightly away from wall grows slowly; consequently, influences over very long distance downstream. enhancement vicinity is increa...
