1. 1. A Comparison Between FDS and the Multi-Zone Fire Model Regarding Gas Temperature and Visibility in Enclosure Fires

   University essay from Lunds universitet/Avdelningen för Brandteknik

   Author : Benjamin Waldeck; [2020]
   Keywords : Enclosure fire; FDS; Multi-Zone Fire Model; gas temperature; Visibility; Technology and Engineering;

   Abstract : When designing large buildings with complex geometry there is often a need for performance-based design and the use of computer models. CFD models like FDS that are available and validated for this purpose are typically time consuming and require large amounts of computing power. READ MORE

3. 2. Feasibility study of modelling a virtual climate chamber with CFD

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Christina Silfwerbrand; [2020]
   Keywords : Virtual climate chamber; CFD; feasibility study;

   Abstract : The company tests their industrial tools in a climate chamber to assure that tools meet the ISO-standard requirements and to assure personnel safety. Since it takes time to prepare the physical tool and to get a time slot to test it, this process was a bottleneck. READ MORE
