Fig. 13From: Experimental Research on Stability and Natural Convection of TiO2-Water Nanofluid in Enclosures with Different Rotation AnglesChanges of Nusselt numbers with heating power (A = 1:4). Average Nusselt numbers changes of nanofluid in the enclosure (A = 1:4) with heating power at different rotation angles. a α = −45°. b α = 0°. c α = 45°. d α = 90°Back to article page
