As the applications of Hydrogen as a replacement for fossil fuels and energy storage increases, more safety issues should be studied. Due to its small low value of the lower flammability limit (LFL), Hydrogen safety hazards due to leakage, especially in closed buildings, should be studied to avoid any damage that can result from the detonation of Hydrogen after mixing with air. The presented work is a part of the Living Lab Energy Campus (LLEC) project at Jülich Research Centre that aims to study Hydrogen leakage scenarios inside the central heating building in research centre's campus. The simulation of the spread of Hydrogen cloud is carried out using the open-source containmentFoam CFD package. The CAD model of the complete structure and equipment details of the central heating building at Jülich Research Centre’s campus was used to generate the computational grid required for the leakage simulation. Then, the leaked Hydrogen behavior inside the building is then simulated using state-of-the-art turbulence models taking into account the buoyancy of such a light gas. The study shows the locations, in which the Hydrogen cloud can accumulate and exceed the LFL value. This study also provides a recommendation of the proper ventilation method in case of accidental leakage to keep the Hydrogen concentrations within the safe limits. |
