Abstract

To characterize the function of water droplets in the restraining and attenuation of the explosive shock wave inside of a cabin, we built several models of a sing layer in z-axis with different sizes of a single droplet and rows of droplets using numerical simulation, analyzed the shock wave interacting with them, observed the interaction process and the change of the droplet forms, summarized the shock wave's attenuation regularities, and obtained some conclusions. The results show that, in the single droplet model, smaller droplets were broken more rapidly and regularly, while bigger droplets tend to break out little droplets more and earlier but less regularly on the whole; that single droplets of different sizes had an effect of attenuation on the shock wave, with an obvious correlation between the increase of the droplet size and that of the attenuation; and that the rows had the most obvious effect of attenuation on the shock wave, with a linear relation between the increase of the droplet number and that of attenuation effect at the same droplet density.
