Abstract
This paper presents a model for aerosol inertial collision removal under mixed gas jet conditions with high Weber number,based on the hydrodynamic model of jet penetration length and entrained droplet fraction.An analysis code of the aerosol pool scrubbing is constructed by spatial discretization of the injection zone.The experimental cases are adopted to validate the model,including two cases of 64%steam fraction,0.7 m submergence depth,and mass fluxes of 217 kg/(m2·s)and 120 kg/(m2·s),conducted by small scale aerosol pool scrubbing facility,and one Reinforced Concerted Action 2(RCA2)experiment with non-condensable gas-carrying aerosols at 0.5 m submergence depth and mass fluxes of 95 kg/(m2·s).The results show that the predictions of the model considering the jet hydrodynamic characteristics are in good agreement with the experimental values.Parameter analysis shows that as the Weber number of immersed jet increases,both jet penetration length and entrained droplet fraction increase,thereby enhancing the inertial collision between aerosols and droplets.关键词
