Abstract

A new closed tunnel was constructed in a real project, and most of the current studies on flow field have focused on the conventional two-opening tunnel. This study represents a pioneering investigation into the influence of ambient wind on the flow characteristics within a one-end blocked tunnel. Numerical analyses were systematically conducted encompassing diverse ambient wind speeds and directions. The findings distinctly reveal the compartmentalization of the internal flow pattern into a vortex zone and a stable zone. Moreover, the vortex zone's length displays a linear relationship with ambient wind speed and wind direction angle within a specific range. Through an amalgamation of theoretical scrutiny and empirical validation, a predictive model for the dimensionless vortex length is formulated, grounding its formulation on ambient wind speed and wind direction angle.
