Xinyan gave a webinar in SFPE Greater London Student Chapter

March 2021

Dr Xinyan Huang was invited by SFPE Greater London Student Chapter to share his latest research on the risk and hazards of dripping fires and a new theory for dripping ignition process. The webinar also covers the latest research by Peiyi and Caiyi.

Why the flame can anchor on a falling drip?

March 2021

The dripping of molten thermoplastics is a widely observed fire phenomenon. The large drips can carry a blue chain flame when falling to the ground and ignite other combustible materials. However, the mechanism by which the flame can stay stably on a falling drip is still unknown. Due to the fast motion and tiny size of drip, experiment is hard to help seek insights. Thus, this paper proposed a DNS model to easily simulate the entire dripping process, including the initial ignition and the subsequent transition to a wake flame, and then, to flame shedding and the final extinction. This work helps reveal the flame dynamics during the dripping and has been published in Flow, Turbulence and Combustion.

Can we forecast the tunnel in real time?

March 2021

Fire incidents in tunnels are fatal disasters causing significant casualties and economic losses. The threat of tunnel fire could be alleviated if we can forecast fire scenarios and make early warnings before emergency circumstances occur. This paper proposed an artificial intelligence model and established an extensive training database. After fine-tuning, the model can timely and accurately predict the temperature field in tunnels 1 min in advance. Based on the temperature field, critical events, such as the temperature in a tunnel is too high for human beings, can be further identified. This study demonstrates the promising prospects of AI in helping firefighting and is published on Building simulation.

Siyan receives the PhD fellowship from the University of California, Berkeley

March 2021

Siyan Wang, an undergraduate student assistant in our fire lab, was admitted to the doctoral program with full scholarship at University of California, Berkeley in the area of Energy Science & Technology with Prof. Michael Gollner. She is also awarded the Berkeley Graduate Division Block Grant Award!

 

Many Congratulations to Siyan!  

Zilong won Best Paper Award from Conference on Thermal Safety Science & Technology

Jan 2021

This paper is a collaborative work between PolyU and Sichuan Fire Research Institute. Zilong applied the artificial intelligence (AI) algorithm to predict the spilled flame from the compartment, based on the training of large-scale facade fire experiment data.

Yanhui presented this paper at the conference in Hefei.

Ricardo Best Paper Award is for (1) significant technological advance, and (2) contribution to the advancement of understanding at a fundamental level

Sir Harry Ralph Ricardo (1885 – 1974) was one of the foremost engine designers and researchers in the early years of the development of the internal combustion engine.

Is façade design a ‘Frankenstein’s monster’?

Feb 2021

Recent fire experiments were conducted at PolyU to re-assess the fire hazard of common ACPs under well-controlled external irradiation. It was found that these materials can still be ignited and burn when exposed to a fire, after the front aluminium layer peeled off. Due to the complexity, the fire hazard associated with the façade system is not only controlled by the core material but also affected by the structural failures at the system level. Under lower irradiation, even without ignition, the long-term heating can still cause severe deformation to lower fire performance. This work is published in Fire Technology.
