Abstract:

The study present a numerical method of calculus of the propagation speed of the pressure wave on a constant section line. We use a systematisation of Jukowski's theories, elements of Riemann and G.Constantinescu studies for the pressure wave propagation. The fluid is considered barotrop. We use the equations of the continuity and move, the general equation of the fluid. In these case when the equation that define the movement have partials derivative still the second order, we use the finite-differences method for obtaining the algebraic relation associated and for the calculus of the speed, in specificated limits conditions and initials Cauchy's conditions
