摘要: ABSTRACTIn this work, we study the stabilization behavior of micro-diffusion flame n-heptane formed in a combustor with inside diameter 4 mm, order to elucidate unique stability mechanism due miniaturization diffusion downstream porous medium. Effects incoming Reynolds number and fuel flow rate on overall shape, exhaust temperature, wall temperature are examined experimentally. Furthermore, an energy balance model micro is established optimal working conditions proposed. Liquid used as two types outer tubes employed examine role heat recirculation. It turns out that tube increases broadens limits. The changes position combustors. At low number, allows stay close medium and, accordingly, substantially h...
