Aixsymmetric Stagnation Point Flow of a Viscous Fluid on a Moving Cylinder with Time Dependent Axial Velocity
The unsteady viscous flow in the vicinity of an axisymmetric stagnation point of an infinite moving cylinder with time-dependent axial velocity is investigated. The impinging free stream is steady with a strain rate k. An exact solution of the Navier-Stokes equations is derived in this problem. A reduction of these equations is obtained by use of appropriate transformations. The general self-si...

The distribution of the initial short-time displacements of a single particle is considered for a class of classical systems of particles under rather general conditions. This class of systems contains canonical equilibrium of a multi-component Hamiltonian system as a special case. We prove that for this class of systems the nth order cumulant of the initial short-time displacements behaves as ...
متن کاملParticle-Based Fluid Simulation on GPU
Rendering realistic moving water is one of the key techniques that immerse the viewers into interactive graphics world including computer games. Physical simulations based on computational fluid dynamics (CFD) is useful for rendering the realistic behaviour of water. However, real-time fluid rendering has been one of the challenging tasks because of high computational cost of CFD. According to ...
متن کاملA Research on Particle-Based Parallel Methods for Fluid Animation
In this paper, we present an acceleration strategy for Smoothed Particle Hydrodynamics (SPH) on multi-GPU platform. For single-GPU, we first use a neighborhood search algorithm of compacting cell index combined with spatial domain characteristics. For multi-GPU, we focus on the changing patterns of SPH's computational time. Simple dynamic load balancing algorithm works well because the computat...
متن کاملRealtime particle-based fluid simulation
Fluid simulation based on smoothed particle hydrodynamics (SPH) is a practical method for the representation of liquids in interactive applications like virtual surgical training or computer games. In recent years various papers introduced ideas for both, the SPH simulation and its visualization. This thesis explains detailed a straightforward CPU-executed implementation of the simulation, as w...
