TL;DR: In this article, an evacuation experiment in a full-scale tunnel filled with smoke has been done in order to clarify the relation between extinction coefficient up to Cs = 1.0, which includes Cs= 0.4m−1 as a Japanese road tunnel fire prevention standard, and evacuation speed.

••
TL;DR: In this paper, a quantitative method for assessing road tunnel fire safety based on a numerical simulation of in-smoke evacuation is proposed, where evacuees are generally in the same space as the fire source but evacuation direction is almost one dimension, a new one-dimensional evacuation simulation was developed wherein the self-determined evacuation necessity detection factors were modeled.

••
TL;DR: In this paper, the authors investigated experimentally the evacuation speed in a full-scale tunnel filled with smoke and clarified the relation between the extinction coefficient (up to 1.6m−1) and normal walking speed.
32 citations
••
TL;DR: In this article, a series of experiments was performed to investigate the evacuation speed distribution in a darkened smoke-filled full-scale tunnel where participants are expected to perform urgent evacuation, the results of which provided fundamental patterns for evacuating pedestrian traffic in the event of tunnel fires.

••
TL;DR: In this article, the authors measured walking speeds of participants wearing blindfolds in a disused ex-Tonokuchi tunnel in Fukui, Japan, in 2016 and 2017 and found that participants' walking speeds were approximately lognormally distributed within a 95% interval.

TL;DR: The boundary layer equations for plane, incompressible, and steady flow are described in this paper, where the boundary layer equation for plane incompressibility is defined in terms of boundary layers.
Abstract: The boundary layer equations for plane, incompressible, and steady flow are
$$\matrix{ {u{{\partial u} \over {\partial x}} + v{{\partial u} \over {\partial y}} = - {1 \over \varrho }{{\partial p} \over {\partial x}} + v{{{\partial ^2}u} \over {\partial {y^2}}},} \cr {0 = {{\partial p} \over {\partial y}},} \cr {{{\partial u} \over {\partial x}} + {{\partial v} \over {\partial y}} = 0.} \cr }$$

TL;DR: In this article, the authors conducted a statistical analysis of tunnel fire accidents in China 2000-2016 and found that over half of TFAs in China result from vehicle technical problem, and the most TFAs occurred in the summer and winter seasons and the autumn season experiencing the least.

TL;DR: In this article, an evacuation experiment was performed in a road tunnel in Stockholm in July 2014, where sixty-six participants, who were instructed to individually evacuate the tunnel, took part, and participants' walking speeds were measured in a smoke-filled section, as well as in smoke-free section, of the tunnel.
