Abstract

Abstract

A theoretical model based on some reasonable concepts was developed to predict the bubbly flow to churn flow pattern transition in vertical narrow rectangular channel under flow boiling condition.The maximum size of ideal bubble in narrow rectangular channel was calculated based on previous literature.The thermal hydraulics boundary condition of bubbly to churn flow pattern transition was exported from Helmholtz and maximum size of ideal bubble.The theoretical model was validated by existent experimental data.
