文摘

For the low Graetz range (<2), a proportional relationship between Sh and Gz is found. For Gz<2, Sh depends on diffusion but fluid velocity remains important. For Gz numbers above 2, Sh satisfactorily described by extension to Lév&ecirc;que. Experimental Kov can be transformed between length scales (dh and L) at low Gz.
