Summary

THE PRESENT PAPER DESCRIBES THE THEORETICAL ANALYSIS OF ERROR FACTORS OF THE FORCED RAYLEIGH SCATTERING METHOD TO MEASURE THE THERMAL DIFFUSIVITY OF LIQUIDS. THE ERROR FACTORS CONSIDERED HERE ARE: 1) EFFECT OF SAMPLE WALL ; 2) EFFECT OF DYE ; 3) EFFECT OF GAUSSIAN BEAM INTENSITY DISTRIBUTION ; AND 4) EFFECT OF HEATING DURATION TIME. THE ENTIRE ANALYSIS IS DIVIDED INTO 2 PARTS: NAMELY WEAK ABSORPTION ANALYSIS AND STRONG ABSORPTION ANALYSIS. IT IS CONCLUDED THAT THE EXPERIMENTAL CONDITIONS CAN BE SO CHOSEN THAT THE AMOUNT OF TOTAL ERROR IS NEGLIGIBLE. (JSME INT. J., SER. II, JP., 31, N 2, 1988/05, 335.
