Abstract

This chapter focuses on computational fluid dynamics (CFD) modeling for gas explosions. Recent results obtained at both laboratory and industrial scales are reviewed. It is pointed out the central role of large eddy simulation (LES) as the most adequate tool for describing the inherently unsteady interplay of flame propagation, flow field, and geometry underlying explosion phenomena. Modeling, numerical, and computational issues yet to be afforded are discussed as relevant to realize fully the potential of explosion LES.
