Mass Transfer at Moderate and High Reynolds Numbers

Mass Transfer at Moderate and High Reynolds Numbers 

Spherical particle at various Reynolds numbers. In the case of a spherical particle in a translational flow at 0.5 Re 200 and 0.125 Sc 50, numerical results concerning the mean Sherwood number (e.g., see [114, 281]) can be described [94] by the approximate formula 

The analysis of available experimental data on heat and mass transfer to a solid sphere in a translational flow results in the following correlations [94]. Heat exchange with air at Pr = 0.7  

Mass transfer with a liquid for large Schmidt numbers (Sc 100)  

Spherical bubble at any Peclet numbers for Re 35. For a spherical bubble in a translational flow at moderate and high Reynolds numbers and high Peclet numbers, the mean Sherwood number can be calculated by the formula [94]
