PIV and LIF System for Synchronous Measurement of Velocity and Density Field



    The third prize of science and technology progress in 2000, Liaoning Province

    Measurement system of velocity field and density field based on PIV and LIF includes: laser expanding system, CCD imaging system, image acquisition and processing system, which enable it to measure the density field and velocity field in the flume simultaneously. The maximum of measurable area for a flow field is 550mm×600mm; the range of measurable velocity is 1cm/s - 150cm/s; the speed of image acquisition is 40 frames per second; the optimal measurable density range is 0.28 - 0.028mg/L and the resolution is up to 0.002mg/L when using Rhodamine B solution as reagent.
