Mr. Yixiang Xu | Computational fluid mechanics | Research Excellence Award

Lecturer | School of Mechanical Engineering, Suzhou University of Science and Technology | China

Mr. Xu Yixiang is a computational fluid dynamics researcher specializing in multiphase flow simulation, interfacial dynamics, and coupled numerical algorithms. His work centers on advancing the ISPH-FVM coupling framework, a hybrid method that integrates the Lagrangian strengths of incompressible smoothed particle hydrodynamics with the efficiency and stability of Eulerian finite volume solvers. Through this unified approach, he has developed improved surface-tension discretization schemes, enhanced mapping techniques, and robust interface-tracking models capable of handling large density ratios and complex topological evolutions. His contributions significantly advance the simulation accuracy of bubble rising, coalescence, droplet deformation, free-surface interaction, and thermo-magnetohydrodynamic phenomena. Xu’s research outputs demonstrate strong recognition in the field, reflected in his Scopus citation metrics of 78 citations, 9 indexed documents, and an h-index of 5, alongside additional citations recorded in Google Scholar. Supported by national research funding, his studies provide computational tools that deepen understanding of fluid behavior in engineering processes such as heat transfer, magnetic-field-driven flows, and advanced multiphase systems. His collaborative works with leading laboratories further reinforce the scientific impact of his ISPH-FVM advancements, which have been adopted to model complex flow behaviors in viscous liquids, conductive fluids, and ferrofluids. Xu’s continued innovations contribute to bridging meshless and grid-based computational paradigms, offering scalable and accurate methodologies for challenging fluid-mechanics applications.
