Abstract

Heat-transfer measurements have been made in normal liquid He contained within a rotating, cylindrical, cryogenic Bénard cell with variable aspect ratio. Data are presented for a range of dimensionless angular velocities 0 ≤ Ω < 600 and Prandtl numbers 0.49 ≤ Pr < 0.76 and for three aspect ratios Γ of 7.81, 4.93 and 3.22. Where possible, comparisons are made with theoretical predictions and past experiments concerning heat transfer in rotating fluids.
