Velocity Field Measurements of Flow inside Snout of Continuous Hot-Dip Galvanizing Process Using a Single-frame PIV Technique.

Development of a Low Cost and Safe PIV for Mean Flow Velocity and Reynolds Stress Measurements

In this study, a white light particle image velocimetry (WL PIV) system which employs a light sheet generated with a flash was used. The system was developed in order to provide a cost-efficient and safe alternative to laser systems while keeping the accuracy limits required for hydraulic model tests. To investigate the accuracy of WL PIV method under different flow conditions, experiments were...

Simultaneous velocity measurements and the coupling effect of the liquid and gas phases in slug flow using PIV-LIF technique

The analysis of a two-phase slug flow is of immense importance due to its vast applications in many industrial problems. A number of experimental and analytical studies have been carried out to study this complex and unwanted phenomena. Mostly these studies were limited to the liquid phase and to the statistical parameters and formation mechanism. So far no attempt has been made to study the ph...

PIV measurements of a microchannel flow

A particle image velocimetry (PIV) system has been developed to measure velocity fields with order 1-lm spatial resolution. The technique uses 200 nm diameter flow-tracing particles, a pulsed Nd: YAG laser, an inverted epi-fluorescent microscope, and a cooled interline-transfer CCD camera to record high-resolution particle-image fields. The spatial resolution of the PIV technique is limited pri...

REACTION KINETICS OF THE FORMATION OF INTERMETALLIC Fe – Zn DURING HOT - DIP GALVANIZING OF STEEL

P. Pokorny, J. Kolisko, L. Balik – Czech Technical University – Klokner Institute, Prague, Czech Republic P. Novak – Institute of Chemical Technology, Prague, Czech Republic This review article mainly describes the composition of intermetallic Fe Zn, i.e. zeta (ζ), delta (δ1k + δ1p), gamma1 (Γ1) and gamma (Γ) on galvanized steel during low temperature galvanization (t ~ 450 °C). It gives detail...
