On the Sherwood number correction due to Stefan flow

This study contributes with insight and new models for mass transfer to spheres three different conditions i.e. without Stefan flow, even flow uneven flux driven flow. High resolved computational fluid dynamic simulations of resulted in a correlation that improves the prediction compared model suggested by Ranz-Marshall particularly higher Sc numbers. A which accounts convective transport within ‘film’ surrounding particle, an increase film thickness due was successfully derived. It is concluded provides improved accuracy Spalding Abrahamzon relative error Sherwood number can be reduced about half.
