Prediction of the heat storage coefficient of a two-phase system

A model has been developed for the prediction of the heat storage coefficient (HSC) of a two-phase system. A temperature-dependent term has been introduced into the model to account for the variation of HSC with temperature. Experimental investigations have also been conducted to study the HSC of loose-granular systems using a plane heat source, fabricated in the authors laboratory. Measurements have been made on samples of different grain sizes with varying temperatures in the range -20 to 80 degrees C. The calculated and observed results are compared and a good agreement has been found.
