Description

technical field [0001] The present invention relates to a test system for the structural effect of gas explosion characteristics, in particular to a test system for studying the size effect of gas explosion characteristics. Based on the test system of the present invention, it is possible to systematically study the propagation characteristics and laws of gas explosions in connected containers. The safety design of industrial production and equipment provides data support, which is of great significance to the prevention of gas explosion accidents. Background technique [0002] In the process of industrial production, it is very common for cylindrical containers and pipes to be used alone or in combination. If the reaction is out of control, daily supervision is neglected, and the containers and pipes are defective, accidents such as fire and explosion may occur, causing casualties and property losses. and environmental damage. In different processes, as the shape of the co...
