Abstract
Experimental and numerical studies have been carried out to obtain the detail information about the ignition characteristics of the flanged electrodes in the premixed gaseous flow field. The propane-air premixed swirling flow field was prepared in the cylindrical constant-volume chamber. The flow field was measured by using LDV for various swirling rates prior to the ignition experiments. The result shows that the stable velocity reduction has been caused around the electrodes mounting the flanges. It is concluded that the effect of flanges on the flow field affects on the reduction of minimum ignition energy. The supplied heat dissipation of flow field around the flanged electrodes have been evaluated numerically.
