Abstract In High Energy Physics experiments Particle Flow (PFlow) algorithms are designed to provide an optimal reconstruction of the nature and kinematic properties particles produced within detector acceptance during collisions. At heart PFlow is ability distinguish calorimeter energy deposits neutral from those charged particles, using complementary measurements particle tracking devices, a ...

Radionuclide studies were performed to determine pulmonary blood flow in six children who had undergone surgery for pulmonary atresia, ventricular septal defect, and hypoplastic pulmonary arteries with or without major aortopulmonary collateral arteries. Lung blood flow was assessed from both particle perfusion lung scans and the pulmonary and systemic phase of a radionuclide dynamic flow study...

We present Particle Flurries, a case study of our efforts toward a synoptic visualization of pulsatile 3D flow that strives to show viewers all flow features simultaneously. The contributions are: a flow visualization technique for stereo viewing that quickly shows particle flow details throughout a volume; a novel poisson-based seeding strategy that prevents redundancy in the particle visualiz...

Differences in flow rates of this nature have a significant effect on the unevenness moisture content dried material, since material which remains drying chamber for an unnecessarily long time is over-dried and under-drying problem remaining dryer too short time. In article, I analyzed increasing particle-wall friction particle velocity field. The research has shown that dead zones are formed v...

We present a computational investigation of the mechanism governing size-based particle separation in microfluidic pinched flow fractionation. We study the behavior of particles moving through a pinching gap (i.e., a constriction in the aperture of a channel) in the Stokes regime (negligible fluid and particle inertia) as a function of particle size. The constriction aperture is created by a pl...

A confined convective flow is experimentally studied at different Rayleigh numbers. Particle Tracking Velocimetry (PTV) technique is used both to reconstruct Lagrangian trajectories and to evaluate Eulerian flow field. Dispersion properties of the flow are investigated by means of Lagrangian statistics on particle displacements. For each run of the experiment, single particle statistics have be...

We report a novel experimental technique that measures simultaneously in three dimensions the trajectories, the translation, and the rotation of finite size inertial particles together with the turbulent flow. The flow field is analyzed by tracking the temporal evolution of small fluorescent tracer particles. The inertial particles consist of a super-absorbent polymer that renders them index an...
