The aim of this study is to design a fire ventilation system with impulse jet fans for an
underground car park. During the planning, it is necessary to consider all aspects of fluid …

Efficient ventilation systems will contribute to maintaining air quality in the tunnel. In order to
improve ventilation performance in normal traffic condition, the 3D tunnel models were …

Ventilation and fire safety design in road tunnels are one of the most complex issues that
need to be carefully considered and analysed in the designing stage of any potential …

In the presence of a water spray system, the fire-induced pressure losses in a road tunnel
can change, but this effect is currently not considered in the design of longitudinally …

Abstract Computational Fluid Dynamics (CFD) is a useful tool in tunnel fire safety, providing
reliable data as a supplement and extension of experiments. In this work, simulations of …

This chapter describes the general basis of Computational Fluid Dynamics (CFD) codes,
outlines the models used in smoke movement analysis, and the paper attempts to describe …

The aim of this study was to design a fire ventilation system with impulse jet fans for an
underground car park. With respect to the number of parameters affecting the spread of …

The definition of the deterministic approach in safety analyses arises from the need to
understand the conditions that emerge during a fire accident in a road tunnel. The key factor …

Many regulatory authorities are now requiring that the emergency ventilation system in a
road tunnel be validated using computational fluid dynamics (CFD). Several such codes are …

The aim of this study is to provide a novel correlation to evaluate the pressure loss, in road
tunnel, for different traffic jam conditions (Filling Tunnel Traffic, FTT). The proposed …
