Numerical Simulation of Pool Boiling Heat Transfer, Focusing On Surface Structural Characteristics In ANSYS Fluent: A review

Multiphase flows, such as pool boiling, are complex multi-physical -multi-scale problems that require a multitude of numerical techniques to solve different physics combined for a specific set of flow parameters and different regimes. For this reason, a well-established numerical solution for well-validated predictive simulations has not yet been clearly defined. The main purpose of this study is to summarize the methods and basic principles of numerical simulation of pool boiling and explain all the steps of its implementation in ANSYS Fluent software in a clear and transparent manner. In this research, the details of numerical models and the results obtained for the nucleate boiling regime are presented to analyze the single bubble dynamics and calculate the critical heat flux. Heat flux is also included. The results of this study show that numerical simulations have a relatively good agreement with laboratory and experimental data.
