The invention provides a multi-mode metal fuel particle ignition combustion device capable of adjusting the atmosphere. The device comprises an ignition module, an atmosphere adjusting module, a combustion diagnosis module and a control acquisition module. A laser chamber in the ignition module is used for adjusting the direction of the emergent light source of a laser igniter so as to be matched with the corresponding perforated quartz tube, and dynamic ignition or static ignition is achieved. An open hole of the quartz tube communicates with the atmosphere adjusting module, and the atmosphere adjusting module can adjust the gas type and flow in the ignition state. Parameters of the ignition module, the atmosphere adjusting module and the combustion diagnosis module can be adjusted by the control acquisition module, the power and the emitting time of the laser igniter can be accurately adjusted, ignition and combustion of a sample under different heating powers can be achieved according to requirements, the simulation of different ignition states is achieved, video images and spectral data in the ignition process are accurately recorded, and multi-angle experimental basis is provided for the analysis of the combustion characteristics of metal fuel particles.
Description
technical field [0001] The present application relates to the technical field of metal fuels, in particular to a multi-mode metal fuel particle ignition and combustion device with adjustable atmosphere. Background technique [0002] The high calorific value of metal fuel particles is conducive to increasing the energy density of solid propellants, and its combustion products can inhibit unstable combustion in engines. Therefore, metal fuels have become one of the important components in chemical solid rocket propellant formulations one. In order to achieve sufficient combustion and energy release of metal fuel particles in practical applications, it is necessary to study their ignition and combustion characteristics in order to scientifically design propellant formulations and engine structures. [0003] The combustion of metal fuel particles involves complex chemical reactions, multiphase flow, heat and mass transfer processes, and the actual ignition and combustion proces...
