ISPH Simulation of Solitary Waves Propagating Over a Bottom-Mounted Barrier With k–ε Turbulence Model

Solitary wave propagating over a bottom-mounted barrier is simulated using the Incompressible Smoothed Particle Hydrodynamics (ISPH) method in order to study generation and transport of turbulence associated with flow separation around submerged structures. For an accurate capture characteristics during propagation, rather than employing standard sub-particle scale (SPS) model, k - ε model coupled numerical scheme. The results are compared experimental data, good agreement observed terms mean velocity, free surface elevation, vorticity fields turbulent kinetic energy. then employed investigate effects non-linearity geometrical size on separation; calculate reflection, dissipation transmission coefficients evaluate importance energy due vortices. this show that developed ISPH closure capable reproducing velocity accurately, thus can be used perform predictions comprehensive hydrodynamics flow-structure interactions urban hydro-environment systems.
