爆破片额定泄放能力的计算

Calculation of Rupture Disc Rated Discharge Capacity

国内涉及爆破片的设计及计算介绍较少,针对泄放介质气体和液体,本文分别给出了两种计算方法,气相泄放较液相泄放的计算复杂,涉及到临界流动,对爆破片的计算具有一定的参考意义。

The design and calculation of rupture discs are rarely introduced in China. For the release medium gas and liquid,two calculation methods are given in this paper. The calculation of gas phase release is more complicated than that of liquid phase release. It involves critical flow,and the calculation has a certain reference significance for rupture disc calculation.
