Prediction of dryout in annular-dispersed flows in the boiling heat transfer is particularly important. A three-fluid model is often used for analyses of the annular-dispersed flows; its applicability to the prediction of the flows in round tubes has been well validated. However its applicability to the annular-dispersed flows in more complicated channels is uncertain. In the present study, the computer program based on a multi-fluid model is developed for predicting the flow properties of annular-dispersed flow accurately in complicated channels and applied it to the annular-dispersed flow in annuli. And the effect of channel geometry is taken into account. The correlation representing the reduced deposition rate to the inner tube was proposed for better prediction of the annular-dispersed flows in annuli.
