 Improvement of longitudinal fins configuration in latent heat storage systemsM. Kazemi, M.J. Hosseini, A.A. Ranjbar and R. Bahrampoury Renewable Energy, 2018, vol. 116, issue PA, 447-457 Abstract: In this study, the consequences of variation of the longitudinal fins angle on the heat transfer improvement during phase change are investigated. Therefore, the melting process of RT 35 as a phase change material is studied for triple-fin and double-fin cases for different angles and the results are compared with of bare tube case. Results indicated that due to the natural convection domination, the upper fin does not leave a great effect on the total melting time. Considering the triple-fin heat exchangers, as the fins angle increases from 60° to 120°, the total melting time reduces. However, when double-fin cases are under consideration, reducing the angle from 150° to 45° results in melting time reduction. More reduction in the angle increases the total melting time. Results also showed that the best cases among triple-fin cases and among the double-fin cases result in 22.5 and 62% reduction in melting time with respect to the simple heat exchanger.
