Title

Numerical Modeling of Wave Breaking in a Bumpy Channel Using Incompressible Smoothed Particles Hydrodynamics

Pages

  179-196

Abstract

 Wave breaking can occur in Dam break.phenomenon. These waves can be summarized as an uncontrolled release of water flow instantaneously from rest by the sudden removal of a vertical barrier that initially contains water. This occurrence usually causes huge loss of lives and destructions of properties and environment. Therefore, prediction of water level position, velocity and pressure is essential. Recently meshless methods have been used for numerical modeling of free surface flows. One of the oldest meshless methods is the Smoothed Particle Hydrodynamics (SPH). This method is robust to simulate problems with large deformations. Furthermore, SPH method has used successfully to model the fixed-bed Dam break.waves on a dry-bed and wet-bed downstream channel (Lee et al. 2008 and Khayed & Gotoh, 2010). SPH simulations of the incompressible flows can be performed by two methods: 1) approximately simulating incompressible flows with a small compressibility, namely Weakly Compressible SPH (WCSPH); 2) simulating flows by enforcing incompressibility, namely Incompressible SPH (ISPH). In WCSPH method, the flow is considered as slightly compressible, with a state equation for the pressure calculation (Monaghan, 1994). In ISPH method the pressurevelocity coupling is generally achieved by the projection method (Hu and Adams, 2007). This paper presents a two-dimensional ISPH model to simulate Dam break.waves in a bed with a hump.
