Research
The CFD & HSE Simulation Research Group utilizes advanced numerical techniques to address critical challenges in industrial process safety, occupational health and safety, indoor air quality, air pollution, multiphase flows, chemical reaction engineering, porous scale modelling, and public health. Through rigorous numerical simulations, we provide in-depth understanding and predictive capabilities for complex phenomena across these interconnected domains. Furthermore, we are increasingly incorporating AI/ML algorithms with our numerical data obtained to provide enhanced critical insights, achieve more accurate predictions, faster analysis, and optimized solutions for a wide spectrum of vital industrial and public health issues. This interdisciplinary approach fosters a deeper understanding of complex phenomena and facilitates the development of more effective strategies for enhancing safety, health, and environmental protection.
Chemical Reactor Engineering
In the field of chemical reactor engineering, we apply CFD to gain detailed insights into the flow patterns, mixing characteristics, heat transfer, and reaction kinetics within chemical reactors [8, 9]. This allows for the optimization of reactor design and operating conditions, leading to enhanced efficiency, selectivity, and safety in chemical production. Recently, our group is studying using advanced multiphase CFD models for the Ethylene Epoxidation in chemical reactors (Fig 7).
