Onshore Explosion Studies –Benefits of CFD-Modelling
Integral or phenomenological consequence models are extensively used for explosion and dispersion studies at onshore petrochemical facilities. These models will generally ignore the influence of the geometry of the facility on the ventilation and flow patterns, the generation of flammable gas clouds, and any subsequent explosions. Another significant weakness of these models is the inability to...
متن کاملDust Emission Modelling around a Stockpile by Using Computational Fluid Dynamics and Discrete Element Method
Dust emissions can have significant effects on the human health, environment and industry equipment. Understanding the dust generation process helps to select a suitable dust preventing approach and also is useful to evaluate the environmental impact of dust emission. To describe these processes, numerical methods such as Computational Fluid Dynamics (CFD) are widely used, however nowadays part...
متن کاملMeta-modelling for fast analysis of CFD-simulated vapour cloud dispersion processes
Released flammable chemicals can form an explosible vapour cloud, posing safety threat in both industrial and civilian environment. Due to the difficulty in conducting physical experiments, computational fluid dynamic (CFD) simulation is an important tool in this area. However, such simulation is computationally too slow for routine analysis. To address this issue, a meta-modelling approach is ...

متن کاملVOC level control by ventilation improvement of Flexography printing room using CFD modeling
Using Computational Fluid Dynamics (CFD) technique, the dispersion contours and the exposure rate of Flexographic printing workers to VOCs in a printing department is evaluated. Firstly, VOCs distribution is determined in the printing room due to the existing ventilation system. Through next steps, 4 scenarios for lowering VOCs concentration and its exposure rate to workers are analyzed. Concen...
