Background
In addition to being a main charge of a weapon warhead, the combustion agent is also gradually applied to cutting and blasting operations in some special occasions in recent years, such as emergency repair cutting in a battlefield environment, destruction treatment of non-explosive powder and the like. However, how to effectively utilize the high-energy combustion agent to cut and break underwater objects is still a technical problem.
Due to the great difference between the water medium and the air medium, the combustion agent is rapidly diluted by energy under water, but it is noted that when water is heated to a high temperature of about 370 ℃ instantly under certain conditions, the water is vaporized violently, and an explosive Boiling phenomenon, that is, a physical Explosion phenomenon such as steam Explosion (BLEVE), causes a great number of serious accidents in industry, and the occurrence and evolution mechanism thereof has been paid attention by domestic and foreign scholars in recent years. Compared with pure saturated steam explosion, the steam explosion releases more energy due to phase change, and compared with chemical explosion, the steam explosion does not produce environmental pollution. Therefore, the method fully utilizes the steam explosion generated by the secondary action of the high-energy combustion agent and water to provide a research direction for the crushing operation of the underwater environment and simultaneously provides a new idea for the propulsion and launching of the underwater device.
Based on the above consideration, the present invention proposes a measuring device for generating and measuring water vapor explosion and its shock wave, in combination with the heat released by the high energy combustion agent and the reactant. The device can be recycled through ignition excitation, and can be used for formula research of using high-energy combustion agents in underwater crushing operation.

Preferably, an opening is formed in the bottom of the metal shell, and a pressure sensor or a temperature sensor is connected to the opening through threads.
Preferably, the volume occupied by the liquid in the liquid chamber is 70% to 90% of the entire liquid chamber.
In the present invention, the high energy combustion agent not only generates a large amount of heat but also generates a high pressure, so that the gaseous product of the high energy combustion agent has a low molecular weight, such as H2O，H2Is an ideal gaseous product, therefore, besides metals or metal alloys such as Al, Mg and the like used in the conventional thermite, the metal hydrogen storage material is an optimal choice for the reducing agent in the future high-energy combustion agent. On this basis, the heat of formation of the oxidant in the reactants needs to be lower than the heat of formation of water in order to ensure maximum exothermicity of the reaction of the metallic hydrogen storage material with the oxidant. Therefore, CuO and BaO are proposed2，Li2O2And the like as the oxidizing agent. When the system contains metal hydride, nitrate, chlorate and perchlorate are not recommended to be used as the oxidant in order to ensure the compatibility and stability of the system.
Has the advantages that: the high-energy combustion agent device for underwater cutting and crushing research can obtain pressure or temperature signals of reaction products of the high-energy combustion agent after the reaction products of the high-energy combustion agent react with water, so that the interaction mechanism of the reaction products of the high-energy combustion agent and a water medium is quantitatively analyzed and researched.
