Abstract
A previous kinetic model on corrosion and precipitation for a non-isothermal LBE pipe/loop system is improved by considering a turbulent core region and a laminar sub-layer, respectively. Exact solutions of the mass transfer equations in both core and boundary regions are obtained. Based on the present model, both of the local corrosion/precipitation rate and bulk concentration can be calculated. The present study shows that the effects of the axial temperature profile on the corrosion/precipitation rate and bulk concentration by applying this model to DELTA loop at the Los Alamos National Laboratory. Correlations for average Sherwood number at the highest isothermal temperature section for both open pipes and close loops are presented. In addition, the present solution can be extended to the more general cases of high Schmidt number mass transfer in the developed turbulent wall-bounded shear flows.
