海底沉管隧道射流风机通风效果影响因素的研究
Study on Influence Factors of Jet Fans Ventilation Effect in Submarine Immersed Tunnel
摘要
Abstract
According to the immersed tunnel structure features of the vertical space limited and horizontal space spacious,es-tablishing the three -dimensional numerical simulation model of jet fans longitude ventilation in immersed tunnel,studying on ventilation effect of jet fans longitude ventilation in immersed tunnel,analyzing influence of jet fans installation height,angle and axial spacing to velocity field in immersed tunnel,optimizing the jet fans installation in immersed tunnel.The results show that:tprimary and secondary factors affecting the jet fans ventilation effect in immersed tunnel are installation height,angle and axial spacing.So consider the immersed tunnel structure features of the vertical space limited,improving the ventilation effect by in-creasing the installation angle of jet fans combination in immersed tunnel.关键词
