PLIF Systems

    Planar Laser Induced Fluorescence (PLIF) Systems from TSI

    The integrated PIV/PLIF system from TSI is a unique, on-line diagnostic tool that lets a TSI system simultaneously measure global scalar property fields (e.g., temperature, concentration) along with the two- or three-component velocity field.

    A laser sheet illuminates the measurement region and the PIV camera captures Mie-scattered light to determine the velocity field. Fluorescence is collected on a dedicated PLIF data imaging camera. The relationship between fluorescence intensity and scalar properties obtained from calibration is used to convert the PLIF image field into the scalar quantity of interest.

    Simultaneous PIV and PLIF measurements can be used to evaluate mass transfer rates, heat transfer rates, and mixing processes. Dynamic links to MATLAB® and Tecplot® software packages provide a higher level of capability and flexibility in data analysis and display. Other features of the integrated PIV/PLIF optical system package include a dual camera housing, complete software control of all hardware components, image processing, field alignment, just to name a few. For more information, please see the attached literature or contact a TSI representative.
