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 x 10(4)-1.2 x 10(5), jet Reynolds number (Re-j) 1.7 x 10(4)-5.3 x 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. (c) 2007 Elsevier Ltd. All rights reserved.
