Abstract Forced convection mass transfer between circular tubes and liquid lithium was experimentally investigated over a range of Schmidt numbers from 40 to 57 and Reynolds numbers from 5,550 to 22,500. Information concerning the mechanism for mass transfer was obtained by measuring local solution and deposition rates as a function of distance along the tubes. Observed entrance effects for the solution process suggest that it involves the parallel mechanisms of diffusion through a solid film and through occluded liquid in grain boundaries. It is indicated that the relative contributions of these processes changes with increasing temperature. A j‐factor correlation of existing liquid metal mass transfer data for fully developed conditions in circular conduits is presented and indicates that an exponent of 0.112 for N Re best represents the data. This result agrees well with other studies (9).
