An experimental study of turbulent heat transfer in a tube which rotates about an orthogonal axis
Abstract
In this paper a program of work is described which studies the way in which rotation affects local and mean heat transfer in a circular section tube constrained to rotate about an axis orthogonal to its central axis. The results include conditions of radial outward and inward flow. It is demonstrated that centripetal buoyancy adversely affects heat transfer relative to the stationary tube condition when the net flow is radially outwards. The converse is demonstrated for radial inward flow. Coriolis acceleration is shown to improve heat transfer in the case of radially outward flow with the converse for conditions of radial inward flow. The implication of the results when extrapolated to real engine conditions is discussed.
