abstract

A two-dimensional numerical analysis of oxygen transport and corrosion behaviors in a coupled natural convection and lead bismuth eutectic (LBE) flow in a two dimensional container was carried out in detailed. In present study, it is assumed the corrosion product (iron) concentration is at its equilibrium level at the wall. The wall boundary condition for the mass transfer of corrosion production and oxygen concentration was taken based on the active oxygen control model. And also the oxygen transport in the LBE loop flow was simulated for testing and calibrating flow concentration level oxygen sensors. Both of the corrosion/precipitation rates at the wall, distribution of corrosion product and oxygen, and oxygen diffusion time are analyzed. Some useful information was obtained to understand the mechanism of corrosion behavior and oxygen transport.
