A micro ejector for butane catalytic combustor is investigated. Quasi-1-D computation and CFD analysis are conducted to investigate the effect of various design parameters on ejector performances. A truly 3-D micro convergent-divergent nozzle having a throat diameter of 42μm is fabricateed by electro-discharge machining. It is shown in experimental evaluation of the present micro ejector that the volume flow rate of entrained air can reach 43 times the value of butane when the back pressure of ejector is set as 11.6 Pa.
