A modified firefly algorithm to maximize heat dissipation of a rectangular porous fin in heat exchangers exposed to both convective and radiative environment

Abstract: The current study deals with the optimization of significant parameters of aluminium and copper rectangular porous fins using firefly algorithm with reflective boundary condition. The study has been done considering convective heat transfer, in the first case, as well as combined convective and radiative modes of heat transfer, in the second case. To solve the non-linear governing equation, a semi analytical technique, differential transformation method is adopted. The results obtained by differential transfor… Show more

“…This is evident from the findings of a study performed by Deshamukhya et al. 86 where they considered two cases of heat transfer; the first case considering only natural convection while the second case was performed taking into account the radiative effects too along with convection. The results showed better heat transfer rates through the fin in case II when compared to case I.…”

“…Numerical studies for the evaluation of heat transfer rates by thermal radiation, in the most diverse methods and applications, are strongly represented by the works of: (A) Lou et al 6 in the experimental investigation on simultaneous measurement of temperature distribution and radiative properties in an oil-fired tunnel furnace using the radiative imaging model and thermocouples; (B) Sukirt et al 7 in the evaluation of turbulence-radiation interaction in a turbulent diffusion jet flame through Reynolds-averaged Navies-Stokes (RANS) simulations; (C) John et al 8 in the literature review of the main studies (analytical and numerical) of analysis methods and coupling techniques for conjugated heat transfer problems; (D) Liu et al 9 in the use of the bidirectional reflectance distribution function (BRDF)-with the Minnaert model and the Torrance and Sparrow model-to investigate the effects of different boundary conditions on thermal radiation heat transfer; (E) Deshamukhya et al 10 in the use of a modified firefly algorithm in the optimization of heat dissipation by convection and radiation in heat exchangers with rectangular porous fins; (F) Chen et al 11 in the use and validation of the quasi-Shannon interval wavelet collocation method with the discrete-ordinate method to study partitioned rectangular domains; (G) Srinivasa et al 12 in the study of the effects of thermal radiation and viscous dissipation on heat transfer in a porous t-shape enclosure; and (H) Mahdy et al 13 in the evaluation of heat transfer in a porous square cavity with dust particles suspension and thermal radiation, through the application of a thermal non-equilibrium model. This work studied the geometric influence of height on the main flow parameters of a continuous food oven of the tunnel type of indirect heating.…”
