Method for preparing and inflating premixed aerosol of atomized shock tube

The invention discloses an atomized shock tube premixed aerosol preparation and inflation method, which comprises the following steps: aerosol preparation: atomizing liquid fuel jet flow and dispersing the atomized liquid fuel jet flow in a pre-vacuumized gas mixing tank by adopting a sound velocity nozzle and the shearing action of air inlet sound velocity airflow so as to generate premixed aerosol with a preset equivalence ratio, the mass or volume of the liquid fuel is calculated according to an ideal gas state equation, aerosol preset pressure and a preset equivalence ratio; inflating: enabling the aerosol in the gas mixing tank to continuously enter a pre-vacuumized low-pressure section of the shock tube, extracting the aerosol in the low-pressure section of the shock tube, wetting the inner wall surface of the low-pressure section of the shock tube until the aerosol entering the low-pressure section of the shock tube reaches gas-liquid phase balance later, and then stopping gas inlet, and pumping the ae
