Abstract


The aim of this present work is to find out, which arrangement for finned tube bundles is better for achieving higher heat transfer rate and better pressure drop and other turbulent effects. All of work is done only on two Arrangements (i.e. inline and staggered Arrangement). In this paper a new Arrangement (i.e. Crinkled 450 Arrangement) is developed for 36 solid circular finned tube bundles. This paper investigates the problems of heat transfer, pressure drop and thermal hydraulic performance of inline and staggered arrangement of finned tube bundles. To minimize these problems Author gives a new finned tube bundle arrangement named as CRINKLED 450 Arrangement. A Steady State approach, with a two-equation turbulence model, is employed to examine the prediction of results and analysis. A Computational Fluid Dynamics FLUENT 14.5 is used for Performance Analysis of Arrangements. The modeling of arrangements is done on CATIA V5 and it is imported into the FLUENT 14.5 and in this a steady state pressure based solver and standard k-epsilon turbulence model was used. The proposed method based on a finite volume method and integral averaging of gas temperature across 36 tube row is appropriate for modeling of plate fin and tube heat exchangers, especially for exchangers in which substantial gas temperature differences in one tube row occur. Analysis was done on Modelled 36 solid circular finned tube bundles in cross flow positioned at Inline Arrangement, Staggered Arrangement and Crinkled 450 Arrangement.
