Electrochemical mass transfer between an impinging jet and a rotating disk in a confined system

摘要

This paper presents the mass transfer results from an impinging liquid jet to a rotating disk. The mass transfer coefficients were measured using the electrochemical limiting diffusion current technique (ELDCT). Rotational Reynolds number (Re_r) in the range of 3.4 × 10~4 - 1.2 × 10~5, jet Reynolds number (Re_j) 1.7 × 10~4 - 5.3 × 10~4 and non-dimensional jet-to-disk spacing (H/d) 2-8 were taken into consideration as parameters. It was found that the jet impingement resulted in a substantial enhancement in the mass transfer compared to the case of the rotating disk without jet.
