In this paper we present a Computational Fluid Dynamics (CFD) simulations for the case of natural gas explosion in urban area. Blast simulations aid in the development of effective mitigation strategies. By understanding how blast waves propagate through an urban environment. authorities can implement measures such as barriers. https://www.jmannino.com/amazing-price-Handlebar-for-Motovox-MBX10-and-MBX11-Mini-Bikes-amazing-deal/
