Particle Image Velocimetry using the Expert System

Accelerating Particle Image Velocimetry Using Hybrid Architectures

High Performance Computing (HPC) applications are mapped to a cluster of multi-core processors communicating using high speed interconnects. More computational power is harnessed with the addition of hardware accelerators such as Graphics Processing Unit (GPU) cards and Field Programmable Gate Arrays (FPGAs). Particle Image Velocimetry (PIV) is an embarrassingly parallel application that can be...

performance of selected agricultural spray nozzles using particle image velocimetry

the aim of the present study was to investigate the influence of nozzle configurations on spray drift and explain the influences using several atomization characteristics (length of spray sheet, spray angle, velocity distribution of flow field, fluctuation of velocity, and droplet size). nozzles manufactured by one company (lechler gmbh, germany) were tested by spraying local tap water in a win...

Holography and particle image velocimetry

The contribution of holographic techniques to particle velocity measurements is discussed. Two-dimensional holographic particle image velocimetry and three-dimensional holographic velocimetry are described and compared. Their advantages and limits are discussed and the latest progress in this domain is presented, together with perspectives for the near future.

Characterization of the Bidirectional Vortex Using Particle Image Velocimetry

Particle Image Velocimetry and Thermometry using Liquid Crystal Tracers

There are only few techniques allowing an undisturbed and simultaneous monitoring of two important flow characteristics, i.e. temperature and velocity fields. One of such possibilities appeared when thermochromic liquid crystals became commercially available. Initiated almost 15 years ago technique of simultaneous measurement of temperature and velocity fields (Hiller & Kowalewski 1987) recentl...
