摘要
利用公式ΔU=-0.1196n/λ计算了氢气在空气和氧气中爆炸反应产生的火焰温度,进而计算了爆炸反应产生的压力.当氢气在空气中的浓度分别为74%(爆炸上限)和4.1%(爆炸下限),其爆炸反应产生的压力分别为3.46atm和1.71atm;当氢气在氧气中的浓度分别为94%(爆炸上限)和4%(爆炸下限)时,爆炸反应产生的压力分别为3.79atm和1.56atm.
The temperature produced by H2 explosive reaction was calculated by the formula ΔU=-0.1196n/λ.Then, the pressure was counted.When H2 concentrations in air were at 74%(high limit of explosive reaction)and 4.1%(low limit of explosive reaction),the highest pressures produced by the explosive reactions were 3.46 and 1.71atm respectively;when the concentrations in oxygen were at 94%(high limit)and 4.1%(low limit),the highest pressures produced by the explosive reactions were 3.79 and 1.56 atm in order.
