SPECTROSCOPIC DETERMINATION OF THE THERMAL DIFFUSIVITY OF ORGANIC MIXTURES AND REFRIGERANTS.

Author(s) : LEIPERTZ A., WU G., FIEBIG M.

Summary

THE THERMAL DIFFUSIVITY OF SOME TRANSPARENT LIQUIDS (PURE LIQUIDS, EG, R113, AND BINARY MIXTURES) HAS BEEN MEASURED BY RAYLEIGH PHOTON CORRELATION SPECTROSCOPY (PCS). WORKING IN THERMODYNAMIC EQUILIBRIUM AND PROVIDING A CRITERION FOR THE RECOGNITION OF SYSTEMATICAL DISTORTIONS IN THE MEASUREMENT, PCS OFFERS SOME DISTINCT ADVANTAGES OVERTHE CONVENTIONAL MEASUREMENT TECHNIQUES. ADDITIONALLY, THE PCS PROBE MAY BE USED SIMULTANEOUSLY FOR THE MEASUREMENT OF THE MUTUAL DIFFUSION COEFFICIENT IN BINARY MIXTURES WHICH IS NECESSARY IN SOME CASES ALSO FOR THE DETERMINATION OF THETHERMAL DIFFUSIVITY.
