Time‐dependent behaviour of pressure in cases of explosions: A basis for design of pressure vessels and apparatus . The knowledge of the maximum explosion pressure is important for design of pressure vessels subject to danger of explosion. Especially for non‐spherical geometries or plant‐internal pressure relief, the maximum explosion pressure has to be calculated from the time‐dependent pressure caused by a chemical reaction in the vessel. Therefore, a set of ordinary differential equations was solved numerically by means of the method of differences. Examples are drawn from known experimental studies. Turbulence effects are also considered. As a result, an analytical relationship is derived which gives the necessary pressure relief area. Finally the results are compared with those of available formulas. Deviations are explained in detail.
