Piv Analysis of Turbulent Flow in a Micro-channel
نویسندگان
چکیده
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 and develops only at the outlet region of the micro-channel.
