Stable boiling in a rotating cylindrical annulus with continuous through-flow of water was obtained at heat fluxes as high as 818 000 Btu/(hr)(ft^2) (2. 58 MW/m^2) at atmospheric pressure. Incipient- and nucleate -boiling heat -transfer coefficients were obtained at accelerations up to 400 g's. Measurements were made of void fractions, radial temperature profiles, and wall pressures in the boiling fluid. Convective secondary-flow cells and fluid temperature inversions were revealed. Increased fluid thicknesses increased heat-transfer coefficients, but inlet liquid subcooling had no effect. Coefficients increased with acceleration at low heat fluxes, but at high fluxes varied less than the usual data scatter.

Completely updated, this graduate text describes the current state of boiling heat transfer and two-phase flow, in terms through which students can attain a consistent understanding. Prediction of real or potential boiling heat transfer behaviour, both in steady and transient states, is covered to aid engineering design of reliable and effective systems.
