A main reason for an irregular temperature distribution is a nonuniform flow distribution inside the solar thermal system. The paper presents an experimental investigation that analyzes the reasons and effects of partial...

A computational fluid dynamic model of three options for a thermal storage tank with an immersed coiled tube heat exchanger provides insight to the role of baffles on flow structure, temperature distribution, and rate at which energy is extracted. Two baffle systems were considered, as illustrated in Fig. 1...
