ShareA void fraction model for annular flow in horizontal tubes.
Author(s) : HARMS T. M., LI D., GROLL E. A., et al.
Summary
Annular flow is one of the predominant flow regimes encountered in horizontal heat exchangers. Analytical annular flow models typically fail to accurately represent void fraction. Thus, many of the available void fraction models are empirically based. To improve the prediction capabilities of void fraction models, a mechanistic void fraction model has been developed for annular flow in horizontal tubes, including the effect of momentum eddy diffusivity damping at the liquid-vapour interface. The present model is found to work well at moderate mass fluxes.
