微重力板式贮箱推进剂重定位的数值仿真

Abstract

Abstract:

Reorientation of propellant in a vane surface tension tank is of great significance for the ascertainment of propellant distribution, and research on liquid shaking mechanism, and improvement of control accuracy and so on. In order to investigate a law of propellant reorientation, propellant reorientation processes in vane type tank under different microgravity conditions are numerically simulated. The paper introduces a two-phase flow model of three-dimensional unsteady VOF (volume of fluid) , and based on the model numerically simulates all kinds of reorientation processes in a vane type tank during near depletion phase under different microgravity acceleration conditions, then all processes of propellant reorientation under different working conditions and propellant distributions after reorientation are obtained. The simulation results provide advantageous foundation for design of the vane tank.
