Cylindrical fin convection
WebBy considering the interaction between conduction within the fin and convection to the fluid surrounding the fin, an analysis is presented to study the heat transfer characteristics of … Webconvection heat transfer coefficient is uniform across the cylindrical fin surface, radiation from the surface is negligible so it is neglected. Fin base and ambient temperature also assumed to be constant. b) Governing Equation . Fig 1 : Three dimensional view of the cylindrical fin. T .
