Abstract

An experimental study is described in which a laminar two-dimensional diffusion flame has been established by injecting n-pentane vapor uniformly through a porous flat plate into the laminar boundary layer in a confined flow. The influence of the direction of injection of fuel with respect to the gravitational vector on the structure, stability, and extinction limits of the diffusion flame have been studied. The most significant observation of the effect of downward injection of fuel was the absence of the velocity overshoot near the flame zone, which was present for upward injection of the fuel. Also separation of the boundary layer occured below a critical free stream oxidant velocity which was not observed when the fuel was injected in an upward direction.
