Incompressible smoothed particle hydrodynamics simulations on free surface flows
The water wave generation by wave paddle and a freely falling rigid body are examined by using an Incompressible Smoothed Particle Hydrodynamics (ISPH). In the current ISPH method, the pressure was evaluated by solving pressure Poisson equation using a semi-implicit algorithm based on the projection scheme and the source term of pressure Poisson equation contains both of divergence free ve...
متن کاملSimulation of Cold Rolling Process Using Smoothed Particle Hydrodynamics (SPH)
Regarding the reported capabilities and the simplifications of the smoothed particle hydrodynamics (SPH) method, as a mesh-free technique in numerical simulations of the deformation processes, a 2-D approach on cold rolling process was provided. Using and examining SPH on rolling process not only caused some minor developments on SPH techniques but revealed some physical realities. The chosen t...
متن کامل3D Coalescence Collision of Liquid Drops Using Smoothed Particle Hydrodynamics
The importance of modeling liquid drops collisions (see figure 1) is due to the existence of natural and engineering process where it is useful to understand the droplets dynamics in specific phenomena. Examples of applications are the combustion of fuel sprays, spray coating, emulsification, waste treatment and raindrop formation (Bozzano & Dente, 2010; Bradley & Stow, 1978;Park & Blair, 1975;...

متن کاملIncompressible smoothed particle hydrodynamics
We present a smoothed particle hydrodynamic model for incompressible fluids. As opposed to solving a pressure Poisson equation in order to get a divergence-free velocity field, here incompressibility is achieved by requiring as a kinematic constraint that the volume of the fluid particles is constant. We use Lagrangian multipliers to enforce this restriction. These Lagrange multipliers play the...
