Two-phase flow plays a critical role in the operation and safety of nuclear reactors. Understanding and predicting the behavior of two-phase flow phenomena, such as boiling, condensation, and interfacial interactions, is essential for reactor design, performance optimization, and safety analysis. This article explores the numerical simulation of two-phase flow phenomena in nuclear reactors, focusing on the underlying principles, computational methods, and applications. It highlights the importance of accurate numerical models and simulations in providing insights into complex flow behavior, aiding in reactor design, and facilitating safety assessments.
