In this paper, the quenching chamber with double-nozzle was taken as the research object. The axial velocity distribution of the cold gas flow field at three nozzle structural parameters under two inlet pressures has been calculated using finite volume method. Simulation results under five opening strokes are shown and discussed. The nozzle angles and inlet pressure have an influence on the velocity distribution. And the reasonable nozzle angle of arc-quenching chamber is obtained. |
