dc.description.abstractFlowing boiling in microchannels has attacked significant attention as a potential technology for high heat flux dissipation. Its main advantage is the possibility of achieving high heat transfer coefficients using low coolant flow rates. However, the main disadvantage are two-phase flow instabilities and back flow reversals. These instabilities with characteristic pressure drop and flow rate oscillation are undesirable, which is the main idea of our research. Predictions of the boiling heat transfer coefficient in the selected from correlation models are followed by both subcooled and saturated boiling regimes. In particular, the results from the proposed model are elaborated, and the validity of the model for predicting the saturated boiling heat transfer coefficient is assessed by comparison against the experimental data.
