Numerical Investigation of the Heat Transfer Characteristics
WebApr 30, 2024 · The heat transfer process during flow boiling is composed of two main mechanisms, namely, nucleate boiling and forced convection, such as schematically depicted in Fig. 2.12. Based on this fact, the majority of the predictive methods for heat transfer coefficient during flow boiling are based on the superposition of the … WebJul 1, 2016 · Comparing Fig. 20, Fig. 21, the heat flux does not have a strong effect on the heat transfer coefficient which is the case for low heat flux and high mass flux conditions where the convective flow boiling is the dominant contributor and the nucleate boiling is rather suppressed. The heat transfer coefficient is still increased by increasing the ... WebDownloadable!
