The invention aims to provide an experiment device for study characteristics of breakage behaviors of
aerosol-containing liquid bath surface bubbles and an experiment method of the experiment device.The experiment device comprises a preheating water tank, a heating water tank, an
air cavity, a flash rising section, an overflowing water tank, a
backflow water tank and an
ultrasonic generator, wherein the lower part of the
ultrasonic generator is connected with a descending tube; the descending tube extends into the preheating water tank; the bottom of the preheating water tank is communicatedwith a
peristaltic pump; the
peristaltic pump is communicated with a coiled tube through a hose; the coiled tube is arranged inside the heating water tank; the heating water tank is communicated witha
water storage container through a water injection pipeline and a valve; the outlet of the coiled tube is communicated with the inlet of a flash section; the overflowing water tank, the flash risingsection and the
air cavity are sequentially connected from top to bottom; the overflowing water tank is fixed inside the
backflow water tank; the flash rising section is fixed below the
backflow watertank. By adopting the experiment device, behaviors that bubbles are broken to generate liquid droplets in different liquid-phase environments at different temperatures can be measured, and entrainment behaviors of
aerosol under accident working conditions of
nuclear power plants can be well reappeared.
