Optimization of Hydrodynamic Performance of a Venturi Scrubber through Numerical Analysis

Get access DOI: 10.1615/IHMTC-2021.2320
pages 1543-1549


A venturi scrubber cleans radioactive gases and aerosols before releasing them into the environment. By dissolving the liquid being used to scrub the incoming gas stream, the energy of a high-velocity inlet gas stream is utilized to form liquid droplets. The gaseous contaminants are absorbed by the liquid stream in the venturi scrubber. The influence of the geometry of the converging section of the venturi scrubber on i) pressure drop and ii) throat gas velocity is investigated in this study with various boundary conditions. The effect of different venturi scrubber designs (traditional, hyperbolic, and parabolic forms of converging section) has been investigated. The venturi scrubber's hyperbolic design was deemed to be the best of the three because it provided greater hydrodynamic performance by having a larger pressure drop and throat gas velocity. The findings of this study will help to enhance the venturi scrubber in the future.
