Simultaneous Measurement of Velocity and Temperature of Water Using LDV and Fluorescence Technique

  • Conference paper
Applications of Laser Techniques to Fluid Mechanics

Abstract

A method of simultaneous measurement of velocity and temperature of water has been developed using a modified laser induced fluorescence of Rhodamine B. The intensity of fluorescence decreased with temperature and its temperature with a coefficient of 3.2%/K. The dimensionless calibration curve was not affected by laser intensity, concentration of Rhodamine B, laser wavelength and optical configuration. Simultaneous measurement of velocity and temperature was made in a natural convection field.
