Abstract

Two of the factors to be considered at the design stage of the extinction chamber have been examined numerically. one is the sectional area of puffer cylinder, another is that of nozzle throat. the variation of the sectional area of puffer cylinder allowed us to find the size optimal at the interrupting performance. it is shown that the sizes of nozzle throat influenced the pressure rise of puffer cylinder strongly.
