| Abstract: | Discontinuous thrust settling propellant management is popularly applied at present, whose main issue is propellant reorientation.A numerical simulation of propellant reorientation, employing volume-of-fluid(VOF) method, is made to investigate the feasibility of discontinuous thrust settling.Simulation calculation using FLOW-3D software for different cases has been carried out to discuss the factors of the reorientation.The discontinuous thrust settling propellant management is proved feasible by the calcul... |
