Abstract

An experimental study of the transient temperature distribution in an enclosed water body due to the discharge of hot water into it is carried out. The dependence of the profiles on the inlet location and the inlet temperature and flow rate is studied in detail. A stable thermal stratification is found to arise in several cases and the study determines its growth with time and its dependence on the flow configuration. The relevance of the study to solar energy storage, as sensible heat, and to heat rejection processes is also discussed.
