Experiments have been conducted in 7-rod vertical bundles within circular shell. Buoyancy supports the forced flow in one and opposes it in the other. The Reynolds number range nominally covered 900 to 30000; but no distinct transition was observed. The behaviour is explained through a porous medium model. Procedures for estimating bundle-average permeability and fRe values on the basis of porosity have been illustrated for the case of forced flow. Although friction was increased in downflow and decreased in upflow due to buoyancy, change in thermal transport rate was not discerned within Gr/Re = 5: 40.
