A high-speed train that accelerates under crosswinds can potentially encounter dramatic
aerodynamic effects and safety risks. The goal of this study is to reveal the effect of wind …

The coupled effect of canyon winds and rapid switching of operating scenes deteriorate the
aerodynamic performance of the high-speed train (HST) running on the tunnel-bridge …

Multiple toxic gases, such as carbon monoxide (CO), are generated after blasting of plateau
tunnel. To study the influence of high-altitude environment on the diffusion and …

Long-span bridges are strongly sensitive to wind, and it is important to accurately assess the
wind field of bridge sites. Thus, to strengthen the understanding of the wind field of deep-cut …

This paper investigated experimentally the thermal smoke back-layering and critical velocity
of the highway tunnel in alpine gorge area with canyon cross wind. A series of small-scale …

A series of tests were conducted in a model-scale tunnel to investigate the influence of
canyon cross wind on smoke temperature and movement characteristics of tunnel fires …

In the case of immersed tunnel fires, lateral smoke extraction is a method employed to
control the smoke movement with vents set in tunnel sidewalls due to limited space in …

A series of scale model tests were conducted to investigate the influence of canyon cross
wind on burning and flame characteristics of ethanol pool fires inside a tunnel, considering …

The Coandă effect on jet flow can be solved effectively using the jet fan with a pitch angle in
highway tunnels. In this study, the ventilation efficiency of the jet fan with a pitch angle in the …
