Estimation of volumetric heat transfer coefficient in randomly packed beds of uniform sized spheres with water as working medium

The advent of technology and development has led to a surge in energy demands by both developing and developed nations. Since 2000, the energy usage pattern in India has doubled. The majority of the power sector is dependent on the fossil fuel sources for energy generation. While energy generation is of prime concern the storage and retrieval with minimum losses is also significant. The packed beds system form a significant part of the solar power systems which are used to store energy during day time and retrieve it during the night. The present work investigates on the issues related to energy storage capability in packed beds.
