Applied hydromechanics, Vol. 2 (74) ¹ 1, (2000) |
| For calculation of flow in a hydrocannon of shock action the numerical method based on introduction of artificial viscosity to the equations of movement was improwed. The unsteady movement of a compressed liquid is examined in quasi-one-dimensional approximation. The equation of water state is taken in the form which is takes into account possible cavitaion of liquid. The results of calculations carried out for a hydrocannon of a concrete design, are compared to results obtained by the numerical method of the characteristics and by Godunov's method. The peculiarities of application of the considered method for solving problems of unsteady movement of liquid are discussed. |
