Abstract
A complex unsteady multiphase flow field is produced in the process of solid rocket gas jet driven liquid column.In this work,to study the temperature-reducing effect of the liquid column on the jet flow field of the solid rocket motor and reveal the flow evolution and the interaction between gas and water,the coupling flow and phase transition process of the gas and liquid column are simulated using the VOF multiphase flow model coupled with the FLUENT software.The results are compared with the calculation results of the jet flow field where no liquid column exists.The calculation results show that the pressure,temperature and velocity fluctuation in the jet flow field decreased when the liquid column is taken as an equilibrium body.The turbulence in tensity in the jet flow field is reduced.The development of the axial displacement of the jet flow field is reduced by the vaporization of the gas and the liquid column as well as the blocking action of the liquid column.The peak pressure is reduced by 0.9 MPa,the peak temperature by 503 K and the peak velocity by 291 m/s in the core area of the jet flow field,thus verifying the temperature-reducing effect of the liquid column on the gas jet flow field.关键词
