A Multi-Fluid Model of Turbulence for Li-SF6 Submerged Combustion.

Abstract

Liquid metal combustion has been used as the primary energy source for underwater vehicle propulsion because of its energetic and closed-cycle characteristics. This can be achieved by injecting gaseous oxidizer (SF6) in a molten metal (Li) bath. The present paper describes a new multi-fluid (MF) combustion model for multiphase submerged diffusion flames. Each fluid has separate transport equations which are linked to other fluids' transport equations by additional source terms. The present MF model results for a submerged Li(l)-SF6(g) flame gave a much longer plume length compared to the corresponding locally-homogeneous flow (LHF) model results and is in good agreement with the experimentally measured plume length.
