The analysis and application of the ideal steady incompressible hydrodynamic theory

In this paper, based on the ideal steady incompressible hydrodynamic theory for the formulation of efflux and found that the number of the unknown parameters is more than the number of equations, an empirical formula-the computational formula of the model of the Gurney energy conservation is used At the condition of the same structure of the cumulative charge with different cone angles, the velocities of the efflux and slug was got and agreed with numerical simulation and experiment. The followed conclusion was got that the analysis method is valid for the structure design of cumulative charge, the studying explosively formed projectile (EFP), and numerical simulation.
