Spherical Particles and Drops at Arbitrary Peclet Numbers

Spherical Particles and Drops at Arbitrary Peclet Numbers 

To calculate the mean Sherwood number for an arbitrary laminar flow past spherical particles, drops, and bubbles in the entire range of Peclet numbers, one can use the interpolation formula 

Let us consider the behavior of this function in various limit cases. Since Shst - 1 as Pe - 0, we see that Eq. (4.12.6) yields the exact result (4.3.14) 

Maximum error of Eq. (4.12.3) for various types of flow past spherical drops, bubbles, and solid particles
