Two-phase Flow Analysis and Experimental Investigation of Micro-piv for Emitter Micro-channels
Aiming at complex labyrinth-channel emitters’ structure and the practical problem of clogging, this paper investigates the practical flow of water, mixed with sand escaped from filtering, in the labyrinth channel. CFD analysis has been performed on liquid-solid two-phase flow in labyrinthchannel emitters. Based on micro-PIV (particle image velocimetry) flow visualization technology, the flow in...
متن کاملInvestigation of three dimensionality in the near field of a round jet using stereo PIV
A round air jet at a Reynolds number of 19 000 was studied using stereo PIV techniques in an effort to understand the characteristics of all three velocity components in the developing shear layer and to study the evolution of three dimensionality with increasing axial distance. Pulsed laser sheets were aligned to illuminate the centreline plane of the jet. The stereo PIV set-up was suitably ca...
متن کاملPiv Analysis of Turbulent Flow in a Micro-channel
Turbulent flow of water in a short 0.4mm high micro-channel of an emulsifier is investigated experimentally using a micro-PIV technique and compared with numerical predictions. The micro-flow measurements are based on epi-fluorescence illumination and high-speed imaging. Velocity fields obtained from the measurements and direct numerical simulations indicate that flow turbulization is delayed a...
متن کاملVelocity measurements of blood flow in a rectangular PDMS microchannel assessed by confocal micro-PIV system
This paper examines the ability to measure the velocity of both physiological saline (PS) and in vitro blood in a rectangular polydimethysiloxane (PDMS) microchannel by means of the confocal micro-PIV system. The PDMS microchannel, was fabricated by conventional soft lithography, had a microchannel near to a perfect rectangular shape (300μm wide, 45μm deep) and was optically transparent, which ...
متن کاملInvestigation on Turbulent Nanofluid Flow in Helical Tube in Tube Heat Exchangers
In this study, the thermal characteristics of turbulent nanofluid flow in a helical tube in the tube heat exchanger (HTTHE) were assessed numerically through computational fluid dynamics (CFD) simulation. The findings of both the turbulent models: realizable k-epsion (k-ε) and re-normalisation group (RNG) k-epsilon were compared. The temperature distribution contours show that realizable and RN...
