Abstract

Numerical simulations were performed to determine the effect of the Reynolds number (Re) on the wall mass transfer rate of the straight pipe under the fully developed turbulent flow. The simulations were conducted for Re=20,000, 40,000 and 70,000. Because the viscous sublayer is a key zone to the wall mass transfer of the pipe, the low Reynolds Number k- turbulence model was applied, by use of which the mass transfer in the viscous sublayer could be calculated out. The Schmitt number (Sc) was determined to be 1280 in the research. On basis of the simulation results, the average Sherwood number (Sha) along the pipe axis at Re=20,000, 40,000 and 70,000 was determined to be 886, 1668 and 2835, respectively, all a little lower than but close to the corresponding values, 1110, 1934 and 3026, which were derived from the correlation [1].
