English Abstract

This paper introduces a mathematical and numerical analyses of a packed bed containing spherical capsules filled with phase change material (PCM) for latent cool thermal energy storage (TES).

The considered bed is cylindrical tank and containing spherical capsules arranged in a random form.

According to the energy balance on the PCM and the heat transfer fluid (HTF), the governing equations and boundary conditions are derived at transient conditions and used a continuous phase model in this model; the spherical capsules are assumed to behave as a continuous medium.

The governing equations of the HTF and PCM are discretized using the implicit finite difference approach and central difference approximation.

The resulting algebraic equations were solved used MATLAB program.

The numerical results are obtained to study the effects of spherical capsules diameter on the temperature distribution and energy stored in the bed in both charging and discharging modes.
