CFD studies on heat transfer analysis of straight and backward fin with cylindrical channel

  Kunal Dadhania,  Chirag Maradiya

CFD Analysis are conducted to assess turbulent forced convection heat transfer and behaviors for air flow through a constant heat flux channel fitted with different shaped fins. The fin cross-sections used in the present study are straight and backward shapes. Two rib arrangements, namely, in-line and staggered arrays, are introduced. Measurements are carried out for a cylindrical with single fin height 6 mm and 8 mm, fin pitch is 40 mm. The analysis results show a significant effect of the presence of the fins on the heat transfer rate and friction loss over the smooth wall channel. The in-line fin arrangement provides higher heat transfer enhancement. Our analysis carried out with CFD fluent technique. Here analysis set-up carried out with the cylinder, straight and backward fin and heating coil. The use of rib turbulators completely results in the change of the flow field and hence the variation of the local convective heat transfers. The presence of a transverse fin assists to induce the main stream separation first, and to generate a recirculation zone ahead of it and then reattachment over the fin itself. If several fins exist and their pitch is sufficiently larger than the fin height, these flow patterns will reoccur along the channel wall.
