Effect of transverse vibration upon the rate of mass transfer from horizontal cylinders

Data have been obtained for mass transfer from naphthalene to air and phenol to air for horizontal cylinders vibrated vertically over a wide range of Reynolds number. It is shown that these data and the data of all previous investigations, including liquid systems, lie on or near a single smooth curve provided that an appropriate system of coordinates is selected. Further, for high Reynolds number and high Schmidt number, the data approach the theoretical equation of Jameson derived using boundary-layer theory. The authors have found that the mass transfer coefficient for sublimation can be increased by a factor of approximately 30 over that which prevails for the stationary (nonvibrating) case.
