Computing in protection engineering: CFD analysis of blade fragment impact on concrete wall

Computing in protection engineering: CFD analysis of blade fragment impact on concrete wall Nuclear concrete structures must be designed against a large spectrum of severe accidents. The primary purpose of this study is to simulate and evaluate the blade fragment impact on an auxiliary building in nuclear power plants (NPPs) as a part of protection engineering. Numerical computational fluid dynamics (CFD) analysis can reduce a huge amount of time and cost compared to actual experiments. This paper provides the background of the numerical CFD analysis. A concrete auxiliary structure in an NPP is established in LS-DYNA. The effects of the impact on the concrete exterior wall caused by unforeseen accidents with blade fragments crashing into the structure are investigated in depth. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Structural Integrity and Maintenance Taylor & Francis
