Experimental Study on the Pressure Characteristics of Gasoline Vapor Explosion under Weak Restrictions

In this paper, the pressure characteristics of gasoline vapor explosion under weak restrictions was investigated experimentally. The experimental studies have shown that explosion pressure maximized when Rs/R0 was in the range of 1.5~2.0, and when Rs/R0 > 1.5, pressure was proportional to the 2.45 power of the initial radius, and attenuated with the extended distances from the explosion center according to the rule of negative exponent.
