大爆炸压力随管长的增加而增大,而小球中则先增加后减小.
Abstract:
 A series of experiments were carried out in two linked spherical vessels to investigate the influential
factors on H2-air mixtures explosion. This paper focuses on the influence of ignition position,initial pressure and
pipe length on pressure in the linked vessels. The experimental results show that the variation of ignition position
has little impact on the maximum hydrogen explosion pressure in the large vessel,however,the impact on the
maximum hydrogen explosion pressure in the small vessel and the maximum hydrogen explosion rising rate in the
linked vessels is obvious. The maximum explosion pressures in large and small vessel are both increase with the
initial pressure. When the ignition in the large vessel,the change of the maximum hydrogen explosion pressure in
the small vessel is more severe than that in the large vessel. When the ignition in the small vessel,the maximum
hydrogen explosion pressure in the large vessel increases with pipe length. However,the maximum hydrogen explosion pressure in the small vessel increases first and then decreases.
