dc.description.abstract | The underground utility tunnel facility is specified in the Urban Planning Act so as to aim for the aesthetic appearance of a city, preservation of road structure, and smooth flow of traffic. Especially, it has also been recognized as a life line of modern cities and national infrastructure in highly developed modern society. As it was explained above, the underground utility tunnel is a very important infrastructure in modern urbanization. But it is true that a lot of problems are being pointed out such as the reduction of air quality, reduction of ventilation volume, dew condensation and non-emission of poisonous gas due to the lack of smoke ventilating facilities in case of a fire breaking out in a utility tunnel because, in relative contrast to the rise in demand of underground utility tunnels in the city, the factors of underground space had not been reflected properly in the design and construction of underground utility tunnels and its maintenance system. The purpose of this study is to estimate temperature distribution using computational fluid dynamics (CFD) at a cross section in underground utility tunnels. As a result, a temperature distribution at middle point between supply and exhaust is not changed and maintained temperature and a humidity distribution at middle point between supply and exhaust is decreased 30 percent, approximately as by increase of ventilation rate. | - |
