K. Nottmeyer et al., SIMULTANEOUS MEASUREMENT OF VELOCITY AND TEMPERATURE-FLUCTUATIONS IN 2D MIXING LAYER VIA THE THERMOCHROMISM, Fluid dynamics research, 15(4), 1995, pp. 271-276
Velocity and temperature fluctuations in the 2D mixing layer of an aqu
eous solution of cobalt-chloride and sodium-chloride were measured sim
ultaneously by the use of a Laser-Doppler velocimeter (LDV). Owing to
the thermochromism of the solution, the intensity of transmitted Laser
light of LDV gave the information on temperature. It was shown that t
he temperature fluctuation and temperature-velocity correlation can be
measured by this method. Advantages and disadvantages of this method
are discussed.
