Augmentation of Mass Transfer Coefficient in Decaying Swirl Flow

The enhancements in mass transfer coefficients due to the presence of helical tape promoter is presented in this paper. The variables I studied are the flow rate of the electrolyte, rotational speed, Reynolds number, rotational Reynolds number and Scmidt number. It is found I that the mass transfer coefficient increased with increased flow rate and also increased with increase in the rotational speed. Rotation I improved the mass transfer coefficient from 5-107 %. Mass transfer coefficient in the rotation of helical tape swirl generator is enhanced I from 0.5 fold to 13 fold over the mass transfer coefficient in forced convection flow.
