Description
Summary:For an efficient simulation of droplets in their most common spherical shape a spherical-symmetric 1D DSMC-based Vlasov-Enskog solver has been implemented in the PIC-DSMC framework PICLas. So far, primarily planar 1D simulations have been performed and discussed in literature, neglecting the surface curvature and the resulting increased pressure inside the droplet. This has a significant impact on the droplets, especially for sizes in the 10-nanometer range, as this work shows from the results of the evaporation coefficients.
