Experimental study on gas diffusion in subway station

چکیده
In this paper, three-dimensional ultrasonic anemometer and multi-channel have been used to monitor the flow field of a subway station in Beijing. Based on releasing sulfur hexafluoride (SF6) hall, gas transmission diffusion range studied. The results show that under natural ventilation, would be controlled by regular mainstream field. Because obvious subsidence heavy tends accumulate ground. airflow north side platform is stable, which may main channel for will not transmitted downward platform. As result, during emergency response During disposal, it necessary set an evacuation path opposite diffusion. Besides, forbidden turn top smoke exhaust system avoid pollutant ground breathing height.

In this paper, taking Hangzhou Metro Line 1 Wulin Square Station for example, we dynamically optimize the opening number of the entrance ticket windows at the station based on Anylogic pedestrian library, and study the impact of some parameters e.g. the pedestrian arrival rate and the opening number of the ticket windows in peak and off-peak periods, etc., on the average queuing number and util...
متن کاملA Study on Characteristics of Atmospheric Heavy Metals in Subway Station
In this study, we investigated the atmospheric heavy metal concentrations in the particulate matter inside the subway stations of Seoul. In particular, we examined the correlation between the heavy metals and studied the effect of the heavy metals on cell proliferation. In six selected subway stations in Seoul, particulate matter was captured at the platforms and 11 types of heavy metals were a...

Guillot U2R2M CNRS UMR8081, Université Paris-Sud Bât.220, Orsay, France Introduction Using MRI with Hyperpolarized (HP) gases, one can measure diffusion of Helium-3 in the lungs and detect changes due to pathologies such as emphysema [1]. In vivo measurements showed deviation to a simple Gaussian behavior with a single apparent d...
متن کاملAnalysis of Noise and Vibration in Subway Station Hall
This study use noise and vibration analytical system to test and analyze the noise and vibration of subway station hall, draw the conclusion: analysis the noise test results when the vehicles through the subway station hall. The noise rises as the frequency increases, gets the peak value nearby 5000 Hz, the high of test point gives lesser influence to noise contribution. The vibration occurred ...
متن کاملLearning to Detect the Subway Station Arrival for Mobile Users
The use of traditional positioning technologies relies on the underlying infrastructures. However, for the subway environment, such positioning systems may not be available for the positioning tasks, such as the detection of the train arrivals for the passengers in the train. An alternative way is to exploit the contextual information available in the mobile devices of subway riders. To this en...
