Hydrodynamic performance of a one-sided wind catcher was investigated by experimental wind tunnel and smoke visualization testing. Wind catchers or what is... H Montazeri,R Azizian - 《Building & Environment》 被引量: 127发表: 2008年 An Experimental Study of Smoke Movement in Tunnel Fire with ...
Besides, the method for improvement of smoke control was investigated. The results indicate that the smoke still maintains a good layered structure after hitting the excavation face when the fire is very close to the excavation face. In contrast, the stratification of smoke is destroyed after ...
In the present study, the smoke movement and temperature distribution were investigated in utility tunnel fires with five slopes and six heat release rates by numerical simulation. Four different sizes of pool fire experiments were also conducted in a full-scale utility tunnel. The results indicated...
An experimental study addressing important tunnel fire safety issues has been conducted in a full-scale laboratory tunnel at Carleton University. The study developed a Heat Release Rate (HRR) measurement system that will be used for tunnel fire research. Also, the study investigated the effectiveness...
A new partial smoke extraction system for the Busan鈥揋eoje immersed tunnel was investigated experimentally using simulated tunnel fires. The tests were pe... Eui Ju Lee a,Chang Bo Oh a,Kwang Chul Oh b,... - 《Tunnelling & Underground Space Technology》 被引量: 14发表: 2010年 Investigatio...
[14] investigated numerically the effect of the ventilation shaft arrangement and shaft geometry on natural ventilation performance in a subway tunnel by FLUENT. Mao et al. [15] conducted a fire testing to study the temperature distribution of hot smoke under fire circumstance in natural ventilation...
On the western plateau of China, ventilation problems brought on by low atmospheric pressure must be overcome. And CO migration after blasting in high-altitude tunnel by inclined shaft has become a significant scientific issue. In this study, the Computa
aMany believed my great grandfather to be a crazy liar with his tales of ancient spirits and beasts lurking in the dark.At the,I was one of them.But life has its way of changing your perspective.Into returned darkness,into fire,and into eyes.name has not yet been heard by the world....
It was found that the backlayering length was reduced by the obstruction, and the three factors have great influence on the backlayering length. Tang et al. [13] investigated the influence of environment pressure on the temperature distribution in tunnel, and concluded that the temperature decays...
In the countries investigated in this study, tunnel fire safety management (TFSM) builds on experience-based and risk management-based principles that are optimized independently system by system. This is usually done with limited consideration of how these systems are interconnected and affect the ...
