A comparison of mass transfer between a plate and submerged conventional and multichannel impinging jets

摘要

This study presents a work on the comparison of mass transfer distribution on a plate subjected to impingement by a conventional impinging jet (CIJ) and multichannel conventional impinging jet (MCIJ). The local mass transfer coefficients were measured by the electrochemical limiting diffusion current technique (ELDCT). The jet Reynolds number varied in the range of 10,950-50,800 and jet-to-plate distance 2d-10d, where d is the nozzle diameter. The local mass transfer values were recorded beginning from the impingement point to a radial distance of approximately 15d. The distribution of the local mass transfer coefficients (LMTC) was compared for both jet systems.
