الملخص

In this theoretical study, heat transfer and pressure drop in two cases of rock bed thermal storage has been studied, in the first case the equivalent diameter is changed  when the mass flow rate per unit area is constant, and in the second case is inversely. The unsteady numerical simulation is employed to analyze the performance of the heat flow and temperature field in the storage. While the best thermal storage is obtain at equivalent diameter is (0.01) m. and show that the relation of pressure drop is decrease with increase in equivalent diameter except in a range of (0.025 to 0.038) m is constant.
