Multiphase Thermal-Hydraulics: Challenges in Computation and Experiment

Multiphase thermal-hydraulics, such as boiling flows, plays an important role in nuclear safety and reactor design. However, its understanding, facilitated by both computation and experiment, is still relatively modest as a result of complexities encountered in multiphase modeling and measurement. In this panel session, leading multiphase modelers and experimentalists will join in a discussion to identify current multiphase thermal-hydraulic challenges, and to propose new ideas on how to address those. Specific attention is paid to the synergy between modeling and experiment, and to the role that AI may play in the path forward towards safer and more efficient reactor design.
