摘要

In order to explore the influence of ambient temperature on the explosion properties of aluminium/ether/nitromethane gas-fluid-solid multiphase mixtures, we use a 20 L spherical explosion tank to experimentally obtain the effect of temperature on the mixture explosion over pressure, the maximum explosion pressure rise rate and the lower explosive limit. The results show that: under the experimental condition, the explosive characteristic parameters of ether decrease with the increase of temperature. The explosion characteristic parameters of aluminum powder are less affected by the changing temperature. The explosion pressure of gas-liquid-solid polyphase mixture decreases slightly with the increase of temperature, and the maximum explosion pressure rises first and then decreases. There is an optimum concentration ratio for the optimum explosion power. The lower explosive limit of gas-liquid-solid polyphase mixture decreases with the increase of temperature, and the lower limit of mixture tends to be stable after gasification of most volatile substances.
