Spark energy

The spark must always be produced by a spontaneous breakdown of the gas because an electronic firing circuit or a trigger electrode would either obviate the measurement of spark energy or grossly change the geometry of the ignition source (1,2,9). [Pg.517]

Sparks Spark discharges are most common between solid conductors, although one electrode may be a conduc tive liquid. They appear as a narrow, luminous channel, and cany a large peak current for a few microseconds or less. Sparks are the only form of discharge for which a maximum spark energy can be calculated, using the expression ... [Pg.2333]

Figure 3.2.4 shows the calculated results of the time series of temperafure distribution with the total spark energy of 0.7mj and the ratio of capacity spark of 100%. The hot kernel is initially an ellipsoid and the maximum temperature region is located in the center of the spark gap. Afterwards, the hot kernel develops into a torus and the highest temperature region moves into the ring... [Pg.28]
