    Sammanfattning : Temperature is a fundamental thermodynamic parameter used to describe physical, chemical and biological processes. Much effort is made to measure temperature accurately in a wide variety of applications, making temperature one of the most extensively measured parameters. LÄS MER

  7. 20. Droplet size, concentration, and temperature mapping in sprays using SLIPI-based techniques

    Författare :Yogeshwar Nath Mishra; Förbränningsfysik; []
    Nyckelord :Sprays; Optical measurements; Laser diagnostic; Droplet size; Temperature; Fysicumarkivet A:2018:Mishra;

    Sammanfattning : Structured laser illumination planar imaging (SLIPI) is a technique capable of suppressing multiple light scattering effects in optically dense sprays, resulting in spray images without blurs and with enhanced contrast. The novelty of the work presented in this thesis concerns the applications of a variety of SLIPI-based techniques for the measurement of droplet size, droplet concentration, and liquid temperature in atomizing sprays.
