High order moment method for polydisperse evaporating sprays with mesh movement: application to internal combustion engines

Snapshots of the density (initial time, passing interface, final time). The mass is doubling. 1D test case 3: flux continuity condition and velocity jump at interface x s = 0.5,

High order geometrical size moment for polydisperse evaporating sprays - relation with interface average topology The final droplets size distribution downstream the injection

This observation shows that HTLES is able to operate in the scale-resolving mode in the near-wall region and sustain the turbulence by means of the direct control of the

Second, a new Eulerian model, with dedicated numerical schemes, able to deal with polydispersity as well as non-equilibrium velocity distributions for evaporating sprays based on

In summary, the test cases without turbulence source terms due to mean ve- locity gradients but with different initial energy distributions illustrate that the two-phase

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 ∼

For dt = 0.1, we can notice that the resolution collapses when the third canonical moment becomes negative (Fig. The error made by considering the evaporative flux constant during
