“…Walter and Hofmann modelled boiler dynamics [2], demonstrating the effect of different correlations for external Nusselt numbers on predicted boiler behaviour. Martinez et al [3] investigated the optimum fin tube geometry, based on published correlations for Nusselt number and pressure drop. Prieto et al [4], [5] employed empirical correlations to predict temperature distribution in unfinned boiler tubes.…”

This paper proposes the method of finned pipe heat exchanger modelling using porous medium approach. In this approach fins are changed to the porous medium by means of a formal algorithm using ANSYS CFX. The last one permits to develop heat exchanger design take into account the temperature and pressure fields. Then the modelling results can be used for the stress analysis and in the construction optimization process. The paper scope is to introduce a simple, cost-efficient method, which is capable to simulate a gas flow of a heat exchanger and can be integrated into more complex simulations.

“…Any response to this question leads to the study of fin performance and its thermal optimization. Therefore, many different works have been performed in order to analyze heat transfer performance in the finned surfaces []. Some of the previous investigations have focused on the fin profile [] as one of the effective parameters on the heat transfer of the fin, while some of the others have considered thermal characteristics of fins [] or surrounding fluid [].…”

This study presents a new approach on the heat transfer enhancement of annular fins with constant thickness using functionally graded materials. The thermal conductivity of the annular fin is assumed to be graded along the fin radius as a power‐law function. The resulting fin equation is solved by an approximate analytical method using the mean value theorem. The variable coefficients of second and third terms in the second‐order differential equation of the fin are replaced with their mean values along the fin radius. Several different graphs regarding the computed temperature profile, fin tip temperature, and fin efficiency are plotted with respect to the radii ratio thermo‐geometric parameter, and inhomogeneity parameter. It is demonstrated that the inhomogeneity parameter plays an important role on the heat transfer enhancement of the annular fin. However, for large radii ratios the effect of the inhomogeneity parameter decreases. Finally, it is stated that application of the functionally graded material in the annular fins, enhances the heat transfer rate between the fin and surrounding fluid resulting from the higher fin efficiency in comparison to the homogeneous annular fin. It is hoped that the results obtained from this study arouse interest among thermal designers and heat exchanger industries. © 2013 Wiley Periodicals, Inc.
