Summary

THE EFFECTIVE THERMAL DIFFUSIVITY OF DISPERSED MATERIALS BASED ON PULSE HEATED METHOD HAVE BEEN STUDIED BY NUMERICAL ANALYSIS. THE FACTORS CONSIDERED IN THIS PAPER ARE VOLUME FRACTION OF DISPERSED PARTICLES, PARTICLE SIZE RATIO TO TEMPERATURE FIELD, THERMAL DIFFUSIVITY RATIO OF PARTICLES TO MATRIX AND DISPERSION STATE OF PARTICLES. THE DIFFUSIVITY VALUES ARE COMPARED WITH THE CALCULATED VALUES USING EFFECTIVE THERMAL CONDUCTIVITY, EFFECTIVE SPECIFIC HEAT AND EFFECTIVE SPECIFIC WEIGHT. IT MAY BE CONCLUDED THAT THE ESTIMATION OF EFFECTIVE THERMAL DIFFUSIVITY IS REASONABLE FOR PRACTICAL USE IN THE REGION MORE THAN 5 OF THE RATIO OF THE THICKNESS OF THE PLATE TO THE PARTICLE SIZE.
