Prediction of time-dependent diabatic two-phase water flows
From international symposium on two-phase systems; Haifa, Israel (29 Aug 1971). See CONF-710836-. An analytical technique is presented for the prediction of the oscillatory behavior of flow-boiling systems. The analysis is based on the cross-section averaged form of the mass, energy and momentum conservation laws. Constitutive laws, based on a local conditions hypothesis, have been developed to describe the effects of non-uniform void and velocity profiles, the vapor generation rate, and the wall shear stress. Predictions of steady flow axial void and pressure distributions are shown to be in good agreement with available data, as are predictions of void oscillation amplitude and phase lag for modulated heat flux data and conditions at the onset of sustained-flow oscillations for fixed pressure-drop channels.
