Qingqing Liu

Qingqing Liu is an Assistant Professor in the Michael W. Hall School of Mechanical Engineering at Mississippi State University. Their research focuses on thermal-fluids experiments and modeling in nuclear energy systems, space exploration, and advanced energy conversion technologies. Key areas include reactor thermal dynamics, two-phase flow phenomena, cryogenic fluids, and advanced instrumentation development.

Education: Liu holds a Ph.D. in Nuclear Engineering from the University of Michigan (2020), an M.S. in Mechanical Engineering from Shanghai Jiao Tong University (2015), and a B.S. in Mechanical Engineering from the University of Shanghai for Science and Technology (2012).

Research Interests: Their work addresses critical challenges in nuclear reactor thermal hydraulics, such as post-critical heat flux (Post-CHF) heat transfer, inverted annular film boiling regimes, and cryogenic fluid management for space applications. Techniques include experimental measurements (e.g., high-resolution X-ray radiography), computational fluid dynamics (CFD), and machine learning models for predictive analysis.

Publications Highlight Trends: Recent work emphasizes experimental validation of flow regimes, machine learning for temperature predictions in Post-CHF conditions, and CFD modeling of bubbly flow in rectangular geometries. Research also explores cryogenic phase separation technologies and bubble dynamics under pressure gradients.

• Awards: 2022 Outstanding Reviewer Award (Nuclear Engineering and Technology), 2022 Best Paper Award (NURETH-19), 2012 Outstanding Graduates of Shanghai.

Advising and Grants: While specific grants are not listed, Liu’s research indicates active involvement in experimental facilities and collaborations. Their work has been presented at major conferences like NURETH and the Japan-U.S. Seminar on Two-Phase Flow Dynamics.

Labs/Teams: Engaged in thermal-hydraulics research groups at Mississippi State University and Dynaflow Inc., focusing on cryogenic systems and nuclear reactor safety.
