ABSTRACT. TO DETERMINE THERMAL DIFFUSIVITY OF SEMITRANSPARENT MEDIA AT TEMPERATURE THE BACKSIDE TEMPERATURE RISE OF A CYLINDRICAL SAMPLE IS SUBJECTED TO SHORT PULSED HEAT FLUX. THIS SAMPLE IS THUS HEATED TO CERTAIN TEMPERATURE AND TEMPORAL TEMPERATURE VARIATION CAN BE USED TO MEASURE THE THERMAL DIFFUSIVITY. THE MAXIMUM A POSTERIORI (MAP) CRITERION IS USED FOR THE PARAMETER ESTIMATION PROCEDURE.
KEYWORDS: THERMAL DIFFUSIVITY, FLASH METHOD, SEMITRANSPARENT MEDIA. |
