My work focuses on the experimental investigation and multi-scale modeling of turbulent transport and corrosion–erosion phenomena in heavy liquid metal (HLM) systems, with direct relevance to next-generation nuclear technologies.

A central theme of my research is the development of integrated experimental–computational frameworks for investigating flow-accelerated corrosion and erosion.

• Experimentally, I contribute to the design and operation of high-temperature liquid-metal corrosion and rotating-disk erosion facilities that enable mechanistic quantification of corrosion, oxide formation, and erosive material loss under well-characterized turbulent boundary layers. In addition, I conduct experimental investigations into the damage mechanisms of corrosion and erosion-assisted corrosion to build a fundamental understanding of these processes in both conventional and advanced structural materials.

• Computationally, I develop hybrid numerical approaches that couple high-fidelity Eulerian computational fluid dynamics (CFD) solvers with Lagrangian Random Walk Monte Carlo (RWMC) methods to capture non-local turbulent mixing, nucleation kinetics, and precipitation dynamics. In parallel, I am developing immersed-boundary-based computational frameworks to study the two-way coupling between evolving surface topography and turbulence dynamics.

Overall, my work seeks to construct a unified, physics-based framework describing how turbulence, interfacial reaction kinetics, and phase transformation collectively govern corrosion, erosion, and mass transport in structural materials. This mechanistic understanding underpins the development of predictive degradation models, performance-driven material qualification, and improved engineering strategies for next-generation liquid-metal-cooled nuclear systems.
