The flow and distribution of propellant in the vane-type surface tension tank in microgravity condition was studied. The rewetting process of propellant in tank was calculated by numerical simulation using VOF method, and the liquid management capability of the tank and PMD was tested. The interior corner flow of propellant along the PMD was investigated by analytical solutions, and the length of the meniscus in the tank was calculated, and the results were compared with the numerical simulation results. Inevitably, errors were noticed between numerical simulation and analytical solution due to the complication of the model of spherical tank with PMD, but they were in accordance with the tendency of the flow. The present research can provide useful reference for the study of interior corner flow.
