Current research on fires in high-speed train carriages mainly focuses the temperature distribution of smoke, while flow structure and dynamic evolution patterns smoke have not been reviewed. This study employs numerical simulation to systematically investigate fire ejection behavior from broken windows a carriage, influence different window parameters was considered. The results indicate that asymmetric geometric configuration seats both sides source induces lateral displacement toward...
In this study, the three-dimensional unsteady Navier-Stokes equation and fully buoyant corrected Renormalization-group (RNG) k-ε turbulence model were employed to investigate influence of tunnel slopes on temperature distribution characteristics a subway train moving with fire source. The sliding grid technology was used simulate relative movement between tunnel, its reliability verified by experiments. It found that slipstream primarily determines smoke when carries in transit. After stops,...
Scenario models of a moving subway train can help investigate the influence different fire locations on smoke propagation characteristics in curved tunnels. To this end, study adopts three-dimensional Unsteady Reynolds Average Navier-Stokes equations method and renormalization group k-ε two-equation turbulence model with buoyancy correction for numerical analysis. The motion is replicated using slip grid technique. results indicate that when breaks out tunnels, piston wind leads longitudinal...
In order to analyse the feasibility of setting up a ceiling type purification and ventilation system in an urban highway tunnel study parameters passage, this paper used Fluent software carry out 3D numerical simulation. The velocity pressure distribution shunting efficiency were analysed under different angles between passage main tunnel. Also, by comparing CO concentration tunnel, conditions is verified. results showed that purified related angles. With increasing angles, decreases....
Abstract The organic Rankine cycle (ORC) is low-grade heat recovery technology, for sources as diverse geothermal, industrial, and vehicle waste heat. working fluids used within these systems often display significant real-gas effects, especially in proximity of the thermodynamic critical point. Three-dimensional (3D) computational fluid dynamics (CFD) commonly performance prediction flow field analysis expanders, but experimental validation with real gases scarce literature. This paper...
Abstract Experiments were conducted in a 1:20 arced tunnel model to investigate the effect of canyon cross wind on buoyancy-induced smoke flow characteristics pool fires, involving movement behaviour and longitudinal temperature distribution layer. The speed, fire location size varied. Results show that there are two special behaviours with source positioned at different field zones. When is negative pressure zone, increasing always exists upstream mainly due vortex, near increases first...
