Abstract
A photoevaporative mass-transfer measurement technique has been used to determine the convective mass-transfer behavior of stationary and rotating cylinders which were immersed in a two-dimensional jet of air. For a stationary cylinder, the circumferential distributions of the local mass-transfer rate were determined as a function of jet Reynolds number (45000−176000) and ranges of other parameters of practical importance (relative position of cylinder in jet (L/D) and relative size of cylinder and jet nozzle (d/D)). Circumferentially averaged values of the mass-transfer coefficient were estimated by integration and the results used to produce correlations for the mean Sherwood number. For a rotating cylinder immersed in the slot jet, circumferentially averaged values of Sherwood number were directly determined for a range of conditions similar to those used in the study of the stationary cylinder but with rotational speed as an additional variable. Predictions of the mean Sherwood number for cylinders dr...
