Type of article: Article

Summary

THE MEASUREMENT OF THERMAL DIFFUSIVITY BY THE PHOTON CORRELATION TECHNIQUE IS LIMITED SO FAR TO PURE LIQUIDS AND TO SUCH BINARY MIXTURES, FOR WHICH THE DIFFERENCE IN THE REFRACTIVE INDEX OF COMPONENTS IS SMALLER THAN 5%. FOR THE FIRST TIME RESULTS FOR A BINARY MIXTURE WITH A REFRACTIVE INDEX DIFFERENCE LARGER THAN 5% ARE PRESENTED (ACETONE/CARBON TETRACHLORIDE WITH A DIFFERENCE OF 7.4%). FORTHE DETERMINATION OF THE THERMAL DIFFUSIVITY THE EXACT KNOWLEDGE OF THE DIFFUSION COEFFICIENT IS NECESSARY. THE THERMAL DIFFUSIVITY AND THE DIFFUSION COEFFICIENT ARE MEASURED USING THE SAME APPARATUS.
