Particulate two-phase flow
WebA new flow mechanism that explains the formation of the non-ring nugget during FSP A356 was identified. ... detailed evidences suggest that the major mechanism governing the removal of the eutectic beta-Mg17Al12 particles is through a sequence of incipient melting of beta-phase, Al rich liquid wetting recrystallized α-Mg grain boundaries thus ... Web7 Sep 2010 · The two-fluid approach is to treat the particulate phase as a second fluid with an effective viscosity, thermal conductivity and diffusion coefficients. This approach has found application for dense flows such as fluidized beds.
