Effect of wire mesh on gas explosion in spherical vessel connected to pipe opening to atmosphere

To study the effect of a multi-layer wire mesh on gas explosion in spherical vessel connected to a pipe opening to atmosphere, experiments were conducted under different layers and meshes. The results show that the explosion intensity is enhanced in an open system while a wire mesh is added in pipe, and that the maximum explosion pressure increases with the increasing numbers of layer and mesh. A mathematical model was built by the method of curve fitting. The maximum explosion pressure was fitted according to the model. Fitting formula shows that a wire mesh with less layers has a positive effect on the maximum explosion pressure. However, the effect is weakened with the increase of the number of layers. When the number of layers is large enough, the maximum explosion pressure tends to be constant.
