Effects of channel orientation on fluid flow and heat transfer in a channel with angled ribs

  • Numerical simulations of turbulent flow and heat transfer in a rotating radial outward flow passage with 60° ribs were performed. Three channel orientations were studied, that is, 0°,-45° and +45°. Effects of Coriolis and rib induced secondary flows were analyzed with the three dimensional simulations and the following conclusions were drawn: the combined effects of Coriolis and rib induced secondary flows largely depend on channel orientation. The 0° channel orientation produces largest heat transfer variation between leading and trailing edges, the -45° channel orientation gives the lowest overall heat transfer augmentation, while the +45° channel orientation has the highest overall heat transfer enhancement.
