Abstract As a cost-effective hole production technique, friction drilling is widely used in industrial and automotive manufacturing. Compared with the traditional bolted connection, it enables fastening of thin metal sheets thin-walled tubular profiles. Friction results higher thread length joint strength, thus better fulfilling demand for lightweight structures. However, numerical simulation d...
We investigate the effect of chemical freeze-out on identified particle spectra at 200AGeV Au-Au Collisions at RHIC, by utilizing a full three-dimensional hydrodynamical calculation. The hydrodynamical code SPheRIO we employed is based on the smoothed particle hydrodynamic algorithm. In order to describe the spectra of strange hadrons, the code has been further improved by explicitly incorporat...
A brief description of the Smoothed Particle Hydrodynamics method is presented together with some test calculations and astrophysical examples of accretion phenomena.
The fri ctional force on a Brownian motion particle can be expressed by means of the time· correlation of the fluctuating force on the particle . We show that this method, applied to a spherical particle in a vi scous incompress ible fluid , leads to Stokes ' Law. The calculation is based on the theory of hydrodynamic flu ctuations due to Landau and Lifs hitz, and on a hydrodynamic theorem due ...
We discuss the design and implementation of HYDRA OMP a parallel implementation of the Smoothed Particle Hydrodynamics–Adaptive PM (SPH-APM) code HYDRA. The code is designed primarily for conducting cosmological hydrodynamic simulations and is written in Fortran77+OpenMP. A number of optimizations for RISC processors and SMP-NUMA architectures have been implemented, the most important optimizat...
INTRODUCTION Investigation of blood flow behavior in the left ventricle (LV) during the filling phase (diastolic phase) is of great interest to biomedical engineering and cardiology. In the process of detection/ refinement of heart diseases, physicians can only rely on the clinical data and their personal experience. It is important, therefore, to develop decision tools that can help surgeons t...
