| abstracts | In this paper the problem of transient gravitational wave propagation in a viscous incompressible
fluid is considered, with a focus on flows with fast-moving free surfaces. The governing
equations of the problem are solved by the smoothed particle hydrodynamics method (SPH).
In order to impose the incompressibility constraint on the fluid motion, the so-called projection
method is applied in which the discrete SPH equations are integrated in time by using
a fractional-step technique. Numerical performance of the proposed model has been assessed
by comparing its results with experimental data and with results obtained by a standard (weakly
compressible) version of the SPH approach. For this purpose, a plane dam-break flow problem
is simulated, in order to investigate the formation and propagation of a wave generated by
a sudden collapse of a water column initially contained in a rectangular tank, as well as the
impact of such a wave on a rigid vertical wall. The results of simulations show the evolution
of the free surface of water, the variation of velocity and pressure fields in the fluid, and the
time history of pressures exerted by an impacting wave on a wall. |
