Abstract: 
A packed bed thermal storage has several desirable characteristics to be energy storage. The behavior of packed bed is predicted by set of differential equations. A numerical solution is developed for packed bed storage tank accounting to the secondary phenomena of thermal losses and conduction effect. The effect of heat loss to surrounding (k__1), conduction effect (k__2) and air capacitance (k__3) are examined in the numerical solution. It is found that the values of (k__1) and (k__2) are small and can practically be neglected in the solution. The solution indicates the profiles of air and rock bed temperatures with respect to time and length of the bed.
