摘要: Abstract This paper presents the results of heat transfer and pressure drop in concentric annular wide channel with inner plain or finned pipe under stationary rotating conditions Taylor–Couette–Poiseuille flow. The experiments are conducted for one three pipes helical fin spacing 75, 110 150 mm at speeds 0, 200, 250, 300, 350 400 rpm. cover axial Reynolds number 8.07 × 104–1.82 × 105, rotational 0 from 1428 to 3008, corresponds Taylor 1.22 × 106 8.32 × 106. reported form Nusselt numbers friction factors correlated terms Re, Ta, Pr geometrical parameters. proved that Re = 1.5 × 105, 75 mm rotates 400 rpm enhances Nu by a factor 7.5 also boosts ratio exchange pumping power 7.6, compared case pipe.
