| 摘 要： | In present paper, the suppression factor of Chen's model is determined, based on the force and heat balance on a vapour bubble and Clausius-Clapeyron equation, the active nucleate cavity size of flow boiling surface and its disperse characteristic. Furthermore, the correlation is attained using Chen' model and the present suppression factor from the experimental data of R134a and R22 for a smooth tube. The correlation agrees well with the experimental data. It demonstrates the present suppression factor is able to promote the accurate which predicts the heat transfer coefficient of flow boiling in Chen's model.
