| Summary: | Заглавие с экрана The results of mathematical modeling of long gravitational wave interaction with submerged dike is presented. The calculations were performed using OpenFOAM software package. A two-dimensional problem in a viscous, incompressible formulation in the Navier-Stokes equations was solved. Volume of Fluid (VOF) method for tracking the free surface was used. The effect of impermeable submerged dike of various thickness on transmission and evolution of the wave field was observed. The effectiveness of the submerge dike is estimated by evaluating the wave reflection and transmission coefficients using the energy integral method. Calculations showed that after the dike are formed vortex structures of different intensity. In these vortices focuses a large amount of wave energy. This reduces the destructive wave forces almost two-fold. |
