Recent Advances in Analysis of Heat Transfer for Fin Type Surfaces Buy book Edited By: B. Sundén, Lund Institute of Technology, Sweden and P.J. Heggs, UMIST, UK. Summary: Extended surfaces like fins are frequently employed in engineering applications to enhance the heat transfer performance.

This work presents recent advances in modelling the thermal phenomena in single fins, fin assemblies and analysis of transient operating conditions, and more. The current fin industries are working with a prime goal to reduce the overall dimensions of the fins with enhancement of the heat transfer rate per unit weight of the fins.

To meet the industrial demands it has become mandatory to optimize the shape and the size of the conventional fin : Saroj Yadav, Koushik Das, Krishna Murari Pandey. The fin is subject to modification with such enhanced features as vortex generators, micro-grooved fins, or the use of other fin shapes for enhancing heat transfer as reported by a number of authors including Joardar and Jacobi,Yu et al.,Kundu et al.,Mader et al.,Moinuddin et al., and Sharqawy et al.

().Cited by: Aldoss et al. introduced this novel type of heat transfer enhancement technique for the first time, and numerically estimated and compared the thermal performance of a liquid metal capsulated fin with that of a conventional solid fin, investigating the effect of several design and operating parameters.

Two equal-size geometries for the capsulated fins longitudinal sectional area were considered: the rectangular and the half-circular by: The use of fin (extended surface) with extensions, provide efficient heat transfer: Fin with extensions provide near about 5 % to 13% more enhancement of heat transfer as compare to fin without extensions.

Heat transfer through fin with rectangular extensions higher than that of fin with other types. •Finned surfaces are commonly used in practice to enhance heat transfer •In the analysis of fins, we consider steady operation with no heat generation •in the fin, and we assume the thermal conductivity k of the material to remain constant.

•We also assume the convection heat transfer coefficient h. Finned surfaces are commonly used in practice to enhance heat transfer. In the analysis of the fins, we consider steady operation with no heat generation in the fin. We also assume that the convection heat transfer coefficient h to be constant and uniform over the entire surface of the fin.

The rate of heat transfer from a solid surface to. = 1: Fin does not affect the heat transfer at all. (ii) ε 1: Fin act as insulation (if thermal conductivity (k) of fin material is low).

(iii) ε 1: Heat transfer will be increased. Also, 1. ε fin √ 2. ε fin √ 3. ε fin √ Note: 1. Fins are generally used where convection heat transfer coefficient (h) values are relatively low i.e.

2 Heat Transfer From a Fin Fins are used in a large number of applications to increase the heat transfer from surfaces. Typically, the fin material has a high thermal conductivity.

The fin is exposed to a flowing fluid, which cools or heats it, with the high thermal conductivity allowing increased heat being conducted from the wall through.

ture, heat transfer rate is increased by increasing heat transfer coefficient or by heat transfer area. In case of natural convec-tion there is only scope for increasing heat transfer area by providing finned surfaces. The enhancement ratio of heat transfer depends on the fins orientations and the geometric parameters of fin arrays.

Heat transfer analysis on a Triangular fin conducted by Sandhya Mirapalli Kishore P.S [9] shows that the triangular fins are attractive since for an equal heat transfer it requires lesser volume.

A fin is a surface that extends from an object to increase the rate of heat transfer to or from the environment by increasing convection heat transfer, The term (extended surface) is commonly used.
