An analytical prediction for performance and optimum design analysis of porous fins / Balaram Kundu in International journal of refrigeration, Vol. 34 N° 1 (Janvier 2011) 

Public ISBD [article]  in International journal of refrigeration > Vol. 34 N° 1 (Janvier 2011) . - pp. 337-352 Titre : An analytical prediction for performance and optimum design analysis of porous fins Titre original : Prévision, analytique de la performance et la conception optimale d'ailettes poreuses Type de document : texte imprimé Auteurs : Balaram Kundu, Auteur ; Dipankar Bhanja, Auteur Année de publication : 2011 Article en page(s) : pp. 337-352 Note générale : Génie Mécanique Langues : Anglais (eng) Mots-clés : Heat  exchanger  Fin  Porous  medium  Calculation  Improvement  Performance Index. décimale : 621.5 Energie pneumatique. Machinerie et outils. Réfrigération Résumé : Enhancement of heat transfer rate through porous fins is one of the common choices nowadays. As the energy equation is highly nonlinear, researchers never concentrated on analyzing porous fins analytically. In the present study, an effort has been devoted to develop an analytical model for determination of the performance and optimum dimensions of porous fins with consideration of different models of predictions. Every result has been presented in a comparative way so that the merit of the models adopting in the present work can easily be understood. The optimum design analysis of porous fins has also been carried out. The influences of all the dependent parameters on the performances and optimization conditions have been studied for the selection of a design criterion of porous fins in such applications where the requirement of heat dissipation is essentially high.

Optimum configurations of vertical fins under condensation of saturated vapor / Balaram Kundu in International journal of refrigeration, Vol. 34 N° 4 (Juin 2011) 

Public ISBD [article]  in International journal of refrigeration > Vol. 34 N° 4 (Juin 2011) . - pp. 1048-1056 Titre : Optimum configurations of vertical fins under condensation of saturated vapor Titre original : Configurations optimales des ailettes verticales lors de la condensation de la vapeur saturée Type de document : texte imprimé Auteurs : Balaram Kundu, Auteur ; Kwan-Soo Lee, Auteur Année de publication : 2011 Article en page(s) : pp. 1048-1056 Note générale : Génie Mécanique Langues : Anglais (eng) Mots-clés : Condensation  Fin  Heat  transfer  coefficient  Optimization  Performance  Thermal  conductivity Index. décimale : 621.5 Energie pneumatique. Machinerie et outils. Réfrigération Résumé : In the present study, an optimum fin shape envelope was determined via a theoretical procedure that minimized the fin volume subject to constrained heat transfer rate. A unified analysis is presented for both longitudinal and pin fins with vertical orientation of the fin surface. The analysis was carried out on the assumption of a power law fin temperature distribution. Under certain simplified conditions, this optimization model has been validated. Results obtained from the model are also compared with previously published results for the specific set of designed conditions. From optimization study, practical fin profiles are found under the condensation of quiescent vapor atmosphere.
