Abstract
Using self-designed 30cm×30cm gas explosion experiment pipe and data acquisition system, we found Fe-Ni foam metal suppresses better gas explosion. We analyzed mechanism of suppressing gas explosion from material characteristics,. The three-dimensional holing-through structure of foam metal can quench exploding flame and decline exploding shock wave. Foam metal material has dual advantages of material and structure which can suppress transmission of fire and shock wave. Effect on different parameters of Fe-Ni foam metal materials was contrasted from declining overpressure and flame temperature, and suitable Fe-Ni form metal was optimized for engineering application.
