Hansong Tang

Professor Hansong Tang is a faculty member in the Department of Civil Engineering at The City College of New York (CCNY), part of The Grove School of Engineering. He holds a professorial rank and is affiliated with the Earth System Science and Environmental Engineering program. His research focuses on coastal and environmental fluid dynamics, with expertise in numerical modeling of multiphysics systems, including fluid-structure interactions, sediment transport, and infrastructure resilience under extreme events. He has made significant contributions to domain decomposition methods, hybrid modeling frameworks for coastal processes, and computational approaches for complex hydrosystems.

Key research areas include:

• Coastal hydrodynamics and morphodynamics
• Hybrid computational models for ocean flows
• Infrastructure vulnerability under climate change
• Fluid dynamics of energetic suspensions
• Machine learning applications in coupled PDE solutions

His work emphasizes bridging scales in coastal systems (e.g., coupling Navier-Stokes equations with geophysical fluid dynamics models) and addressing challenges in tidal energy generation, storm surge impacts, and hydraulic fracturing fluid behaviors. Recent studies include assessments of New York City coastal bridges' vulnerability to extreme storm surges and investigations into solitary wave impacts on bridge decks.

Publications reflect a focus on numerical methods, experimental validations, and environmental engineering applications, with frequent exploration of interface treatment algorithms and error correction techniques in fluid dynamics simulations.
