Performance Evaluation of Packed Bed Energy System With Nanofluid

Thermal energy storage (TES) systems are much preferred in many engineering applications, which have the ability to bridge the gap between energy supply and energy demand. Cooling or heating energy redistribution requirements can be effectively met using TES systems. The peak load demand can be shifted to off-peak hours by utilizing stored heat energy from TES units.Thermal energy storage (TES) with packed bed/porous medium is the most effective method to storage the sensible heat/latent heat. Nanomaterials prepared in the range of 1 to 100 nm can produce significant changes in the thermophysical properties of heat storage materials. A proper mixture of liquid and nano particles, which are made up of metals, oxides and carbides etc., results in 'nanofluids'. The incorporation of nanostructures/nanomaterials in specified proportions into base fluid can yield improved thermal conductivity, high thermal stability, and good thermal reliability on a long-term basis. Nanofluids are good thermal capacitors compared to conventional thermal storage media like water and air.
