Abstract: | The study presents the damping of the pressure wave in a case of viscous fluid on a constant section line. We use a systematisation of Jukowski 's theories, elements of Reiman and G. Constantinescu studies for the pressure wave propagation. The fluid is considered barotrop and viscous. We use the equations of the continuity and move, the general equation of the fluid. In the case of unidimensional movement, we considered the influence of the viscosity beeing made by the friction between molecules. We use Bernoulli and Euler's method in specificated limits conditions and initials Cauchy's conditions and we present the damping of pressure wave. |
