The study concerns the application of the Smoothed Particle Hydrodynamics (SPH) method within the computational fluid dynamics (CFD).
Furthermore, numerical hydrodynamic simulations performed by FDMs have been commonly carried out in 2D though many phenomena are usually occurring in 3D.
Fig. 2.b shows a comparison between the SPH simulation and the analytical solution for velocity profile at various time steps.
The simulations were carried out using the Macondo Cluster from the School of Civil Engineering at the University of Queensland.

Preliminary Simulation of the Flow in the Root Canal Using New Irrigation Needle Dragos ISVORANU1, a *and Sterian DANAILA1,b 1Elie Carafoli Dept. of Aerospace Sciences, University Politehnica of Bucharest, 1, Gheorghe Polizu Street, 011061-Bucharest, ROMANIA adragos.isvoranu@upb.ro, bsterian.danaila@upb.ro Keywords: irrigation needle, two-phase fluid flow, root canal, wetting properties Abstract.
Our simulation results show great efficiency of the irrigation procedure in terms of the irrigant volume fraction and wall shear stress at the wall of the root canal over entire working length.
This assertion is acknowledged in literature, see for example [9], but no one has ever considered this stage as an indispensable prerequisite for a reliable simulation of the fluid mechanics of the irrigation process.
Previous CFD investigations in root canal irrigation [1, 8, 9, 10, 11, 12, 13, 14] considered only irrigant mass flow rate, size and type of the needle and the distance between the tip of needle and the apical foramen as analysis parameters.
The simulation is performed within Ansys CFX environment.

Simulation setting.
Because the model can maximally pick up the particle diameter of 10mm, so this paper mainly aims at simulation analysis of this kind of particle.
Simulation results According to numerical simulation, the simulation results for the flow field were obtained in Figure3~ Figure5 and the particle motion trajectory was obtained in Figure 6.
