This paper describes a combined experimental and computational study of the heat transfer from an electrically heated disk rotating close to an unheated stator. A radial outflow of cooling air was used to remove heat from the disk, and local Nusselt numbers were measured, using fluxmeters at seven radial locations, for nondimensional flow rates up to C{sub w} = 9,680 and rotational Reynolds numbers up to Re{sub {phi}} = 1.2 x 10{sup 6}. Computations were carried out using an elliptic solver with a low-Reynolds-number {kappa}-{epsilon} turbulence model, and the agreement between the measured and computed velocities and Nusselt numbers was mainly good.
