Abstract
This work is mainly an experimental investigation on the storage of solar energy and/or the waste heat of a thermal power station in a large water reservoir such as a lake or a ground cavity. A model storage unit of (1×2×0.75)m3 size was designed and constructed. The storage unit was equipped with the necessary means for warm water production and delivery, and to control the side surface heat losses. Experiments were carried out for charging and stand by periods of storing process while the development of temperature profile was measured and the flow pattern was observed and photographed.
The performance of the storage unit was correlated in terms of the effectiveness ε and the dimensionless bulk temperature θ. ε is the percentage of net energy input which has been stored and θ shows the ability of the storage unit to develop its bulk temperature. Effects of charging flow rate (200 kg/h ṁw < 970 kg/h), charging temperature (33.3°C < Ti < 52.6°C), storage aspect ratio (A= 0.125 and 0.250) and the side surface heat losses were examined for both charging and stand by periods.
