✦ Synopsis

The fluid flow due to a rotating disk against an external forced flow is solved by the method of orthogonal collocation. Polynomials with a weighting factor of e -(llr', which are orthogonal to each other in (0, co ), are chosen as the basis functions for this semi-infinite boundary problem. The flow constants pertinent to this flow type are calculated and correlated as polynomials for convenience. Two asymptotic mass-transfer formulas-suitable for SC > 0.1 and SC < 1, respectively, have been derived. In addition, the effects of the forced-flow strength and Schmidt number on the mass-transfer rates are also discussed in this paper.

## Abstract Solutions are developed for mass transfer between a fluid undergoing solid body rotation and a coaxial disk which is located on a stationary infinite surface. The fluid mechanics corresponds to a laminar BΓΆdewadt boundary layer. The overall mass transfer is dominated by the outer portio
