Abstract

Recent work on the application of Electro Structured Fluids to high speed rotating machines has indicated the need for more general correlations for the prediction of heat transfer from rotating cylindrical surfaces. A numerical analysis has been made of such combined flow situations and an experimental programme has given corresponding experiment confirmation of the computed results. The analysis was two dimensional with an allowance for a swirling component of velocity around the cylinder. The maximum blowing Reynolds number, based on the length of the cylinder, was 250,000 and the rotational Reynolds number, based on the diameter of the cylinder, varied from 3,000 to 30,000. Buoyancy effects were neglected and turbulent flow assumed, these assumptions being supported by the
