Simulations of 3D non-hydrostatic free surface flows with SPH
In this paper, the application of a new robust and accurate SPH scheme proposed by Ferrari et al. [1] is presented. It provides good accuracy for computing complex 3D non-hydrostatic free surface flows. This has been assesed by the comparison of the numerical solutions of dam-break and impact-wave problems against experimental data and reference solutions. Moreover, to improve considerably the ...
متن کامل3D Finite Element Modeling of Free-Surface Flows with Efficient k − Turbulence Model and Non-hydrostatic Pressure
Validation of 3D finite element model for free-surface flow is conducted using a high quality and high spatial resolution data set. The present research finds its motivation in the increasing need for efficient management of geophysical flows such as estuaries (multiphase fluid flow) or natural rivers with the complicated channel geometry (e.g. strong channel curvature). A numerical solution is...
متن کاملNumerical Simulation of Free Surface Flows and Comparison of Symmetry and Real Boundary Conditions at the Free Surface
For implementation
 of the free surface boundary condition, a new subroutine has been introduced to an existing steady 3-D body fitted code. This code was previously written for steady flow simulation in closed ducts. The algorithm used in this subroutine reduces the instability problem according to the free surface wave generation. For code validation, it was applied to two different open c...

متن کاملSimulation of Gravity Wave Propagation in Free Surface Flows by an Incompressible SPH Algorithm
This paper presents an incompressible smoothed particle hydrodynamics (SPH) model to simulate wave propagation in a free surface flow. The Navier-Stokes equations are solved in a Lagrangian framework using a three-step fractional method. In the first step, a temporary velocity field is provided according to the relevant body forces. This velocity field is renewed in the second step to include t...
