“…When knowing U ef , the design calculation can quickly lead to an effective length, and, as a consequence, the performance of a triple concentric-tube heat exchanger can be estimated more easily when compared to other types of heat exchanger. Many researchers, such as Zuritz [1], Satyanarayana et al [2], Unal [3], Sahoo et al [4], Batmaz [5], Peigné et al [6], Boultif and Bougriou [7] and Touatit and Bougriou [8] have published the equations of the overall heat transfer coefficients (U 1 and U 2 ) based on the series thermal resistances or the expressions analogous to Newton's law of cooling, in order to design and evaluate the performance of a triple concentric-tube heat exchanger. Instead, how the calculation of the effective overall heat transfer is not reported to the best of its knowledge.…”

A relation for calculation of the effective overall heat transfer coefficient in a triple concentric-tube heat exchanger is proposed. The relation of the effective overall heat transfer coefficient is obtained based on total thermal resistance and it is applied within a case study for thermal analysis of two triple concentric-tube heat exchangers with different geometries, hot fluids and operating conditions. Through case study it is found that the values of effective overall heat transfer coefficient can be obtained with acceptable errors, up to 3 % for both heat exchangers.
