✦ Synopsis

Abstraet--A sensible heat storage unit in the form of a bed, randomly packed with spheres manufactured from a local material (an Egyptian clay), is the subject of the present work. The bed is subjected to explicit and implicit constraints. Explicit constraints are imposed on the bed length, the sphere diameter, and the mass flow rate while implicit constraint is imposed on the pressure drop across the bed. Optimization of the bed parameters, to enable getting maximum ratio of the storing to pumping energy, is achieved by the aid of a computer program which is developed based on the direct search method. The optimum bed parameters are found to be: 2.1 m for bed length, 0.019 m for particle diameter, and 900 kg/h for mass flow rate.
