One-dimensional oxygen transport relation is indispensable to study the oxygen distribution in the LBEcooledsystem with an oxygen control device. In this paper, a numerical research is carried out to studythe oxygen transport characteristics in a gas-phase oxygen control device, including the static case anddynamic case. The model of static oxygen control is based on the two-phase VOF model and the resultsagree well with the theoretical expectation. The model of dynamic oxygen control is simplified and thegas-liquid interface is treated as a free surface boundary with a constant oxygen concentration. Theinfluences of the inlet and interface oxygen concentration, mass flow rate, temperature, and the inletpipe location on the mass transfer characteristics are discussed. Based on the results, an oxygen masstransport relation considering the temperature dependence and velocity dependence separately is obtained. The relation can be used in a one-dimensional system analysis code to predict the oxygen providedby the oxygen control device, which is an important part of the integral oxygen mass transfermodels.
