2026 Roccon Interface Resolved Boiling Heat Transfer

This study addresses the challenges associated with interface-resolved simulations, particularly focusing on the boundary conditions at the liquid-vapor interface, which are crucial for accurately capturing phenomena in boiling and evaporation flows. The objective is to elucidate the jump conditions governing mass, momentum, and energy transfer, alongside the numerical techniques employed to compute interfacial mass flux. Utilizing a thorough review methodology, we examine various models, including the sharp-interface method and level-set approaches, which facilitate the imposition of interfacial conditions through a mathematical framework. Key results highlight the effectiveness of techniques like the Ghost Fluid Method (GFM) in maintaining accuracy and minimizing numerical diffusion during simulations. This work not only clarifies the theoretical underpinnings associated with interfacial interactions but also underscores the adaptability of algorithms developed for boiling to similar challenges encountered in evaporation processes. Ultimately, this research aims to enhance the understanding and modeling of interfacial phenomena in thermal-fluid systems, guiding future advancements in the field.
