The swirling secondary flow in curved pipes is studied three-space dimensions using a weakly compressible Smoothed Particle Hydrodynamics (WCSPH) formulation coupled to new non-reflecting outflow boundary conditions. A large-eddy simulation (LES) model for turbulence benchmarked with existing experimental data. After validation of the present against results 90 grades pipe bend, detailed numeri...

The magnetorotational instability (MRI) is an important process in driving turbulence sufficiently ionized accretion disks. It has been extensively studied using simulations with Eulerian grid codes, but remains fairly unexplored for meshless codes. Here, we present a thorough numerical study on the MRI smoothed particle magnetohydrodynamics method geometric density average force expression. We...

We present a brief introduction to Smoothed Particle Hydrodynamics (SPH), where we focus on an approach to treat the physical viscosity. Additionally we describe in detail the basic principles of our parallel implementation of the SPH method. In the second part we summarise some results of test simulations performed to achieve general features of the method, and we end discussing some astrophys...

‎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...

We propose a particle-based method to simulate thin-film fluid that jointly facilitates aggressive surface deformation and vigorous tangential flows. build our dynamics model from the tension driven Navier-Stokes equation with dimensionality reduced using asymptotic lubrication theory customize set of differential operators based on weakly compressible Smoothed Particle Hydrodynamics (SPH) for ...
