Flow dynamic characteristics in flow field of proton exchange membrane fuel cells
International Journal of Hydrogen Energy, 2008Abstract Water flooding and flow dynamic characteristics in the flow field of a transparent proton exchange membrane fuel cell (PEMFC) consisting of an optical window were studied experimentally. In situ observations of the liquid water build-up and two-phase flow patterns inside the flow field were made. The effects of cell temperature, cathode flow

Abstract Sedimentation field-flow fractionation (SFFF) is a promising method for the high-resolution separation of a wide variety of suspended particulates and dissolved macromolecules. By using a new SFFF technique with a time-delayed exponential force-field (rotor speed) decay, quantitative particle-size distribution analyses in the 0.01–1 μm range ...

Turbulent Flow Field Characteristics in a Motored Reciprocating Engine
SAE Technical Paper Series, 1997<div class="htmlview paragraph">Coincident 3-d velocity measurements in the flat combustion chamber of a motored single cylinder engine have been performed using Laser-Doppler-Velocimetry. The 3-d LDV System consisted of three beampairs (514nm, 488nm and 476.5nm) and two fiberoptic probes operated in 90° cross-scatter mode obtaining high spatial ...

Study on Flow Field Characteristics of Low Swirl Injector
Volume 8A: Heat Transfer and Thermal Engineering, 2014The flow characteristics of six kinds of LSIs, which are designed by different pore sizes in the center channel screen, are analyzed. The velocity vectors on the spanwise sections and the vertical sections in a channel at atmospheric condition are captured using a Particle Image Velocimetry (PIV) system. The swirl number of the airflow through the LSIs
