Numerical simulation and experimental study on liquid dispersion of a liquid loaded warhead
The force of the warhead shell is calculated and analyzed by establishing a liquid dispersion fluid dynamics simulation model of the warhead under different driving pressures and different dynamic viscosity liquid conditions.By comparing the simulation calculation results with the experimental test data,it can be seen that the calculation model can provide support for the analysis of the force law of the liquid-charged warhead shell.In this paper,the pressure time history curves and pressure peaks of different parts of the internal axial direction of the warhead shell are established to obtain the pressure time history curves and pressure peaks in the axial direction of the warhead.It can be concluded that due to the superposition of waves,the pressure peak of the internal shell wall of the warhead is higher than the driving pressure value,and the pressure value in the near zone of the injection hole is the largest,and the pressure peak decreases with the increase of the distance from the injection hole.The driving pressure generated by gunpowder and the hydrodynamic viscosity have a positive correlation with the pressure value inside the shell,that is,the greater the pressure and viscosity,the greater the pressure value of the shell.
