Eulerian versus Lagrangian simulation of unsteady two-way coupled coalescing two-phase flows in solid propellant combustion

According to experimental data given in Figure 3 and Table 2, increasing gas flow rate does not influence liquid spreading near the bed inlet but causes jet confinement for

High order moment methods are then developed: (2) a Two-Size moment method is extended to coalescence to treat accurately the physics of polydispersity and coalescence and the

The present paper is devoted to the computation of two-phase flows using the two-fluid approach. The overall model is hyperbolic and has no conservative form. No instanta- neous

In this case with droplets of low inertia, the build up of the overall droplet mass density spatial gradients does not build up to strongly so that the change in order is not due

The Eulerian Multi-Fluid model has proven its capa- bility to simulate the size-conditioned dynamics of poly- disperse sprays including coalescence with a first order resolution

The convective splitting time step is chosen to allow droplet phase convection to occur at its physical time scale which matches numerical criterion of the transport scheme:.. ∆t c ∼

The Eulerian Multi-Fluid model has proven its capability to simulate the size-conditioned dynamics of polydisperse sprays including coalescence with the resolution of one moment of

But in fact, our results can be compared to the Multifluid approach with a first order scheme and no velocity dispersion, as this method captures naturally the effects that are
