520 | |a The German joint research project ORPHEUS started 2015 and aims at the life safety in metro underground stations in case of fire. Its consortium consists out of 14 partners from industry and science as well as fire brigades and a transport company. This contribution presents an overview of the achieved experimental and numerical results and future work. The experimental part of the project is split into real scale and small scale experiments. The real scale experiments are carried out in an underground station in Berlin during the nightly operational breaks. Hot smoke tests are run, while the three-level station is wired with hundreds of sensors for temperature and velocity measurements. Additionally, the tracer gas SF 6 is added to the plume and its concentrations are measured at various positions in the station. Besides the individual experiments, long term underground climate measurements are performed to model the ambient heat and mass flows through the station with respect to the season and current weather on the surface. A detailed small scale experiment (scale 1:15) was built to be used to evaluate different ventilation strategies and techniques. Each of the two approximately 8 m long platforms allow the positioning of the heat and smoke source embedded in a metro car model. The real scale experiments were accompanied by a firefighter brigade, which practiced new tactical approaches under low visibility conditions in a complex underground station. Additionally, new technical equipment supporting the orientation was evaluated under quasi-realistic visibility conditions. Orientation experiments as well as sign perception under low visibility complete the experimental campaign. On the simulation side, the main topics are: the validation of FDS and ANSYS CFX with the experimental data (laboratory and field experiments), modeling of ventilation systems, coupled evacuation and smoke spread analysis, and the development of new numerical methods. The validation simulations focus on the smoke layer heights and temperature profiles and are run on high performance computing facilities to allow for an adequate numerical resolution. While they consider the underground climate conditions during the experiments, the used propane torches are not explicitly modeled. So far, a good agreement with the experimental data was observed. To analyze the life safety in the station, ensemble calculations of a coupled evacuation (JuPedSim) and smoke (FDS) system were run. Within the evacuation runs, different routing strategies were evaluated. The developed analysis methods extend the RSET-ASET concept by a spatio-temporal view point. The final goal is to understand the full system, including e.g. underground climate or orientation, and hence to design smoke control measures to increase the life safety in underground stations in case of fire. | ||
