摘要

In many industrial devices, pressure conditions are such that experimental diagnostics are very limited, which makes computational methods crucial to provide the physical understanding required to improve technologies. These flows however present significant numerical and modeling challenges due to very non-linear thermodynamics and the presence of extremely high density gradients. High-density jumps induce intense fluid dynamic strain strengthens gradients making the use of stabilization methods necessary. The present work focuses on the comparison of classical flux-correction stabilization approaches in the context of Large Eddy Simulation and the development of a more accurate technique to handle high-density gradients in high-Reynolds number flows.
