TY - JOUR TI - Thermal performance of a porus radial fin with natural convection and radiative heat losses AU - Darvishi M T AU - Reddy Gorla Rama Subba AU - Khani F AU - Aziz Abe-El JN - Thermal Science PY - 2015 VL - 19 IS - 2 SP - 669 EP - 678 PT - Article AB - An analytic (series) solution is developed to describe the thermal performance of a porous radial fin with natural convection in the fluid saturating the fin and radiation heat loss from the top and bottom surfaces of the fin. The HAM results for the temperature distribution and base heat flux are compared with the direct numerical results and found to be very accurate.
