Abstract
Recent improvements to the Morphogenetic approach, a Lagrangian - stochastic ice accretion method, are presented. First, the mechanism of determining droplet impingement is redone in a way consistent with Eulerian droplet solvers, secondly, multi-shots have been enabled during the simulation process, and, finally, multiple mesh topologies have been enabled. The numerical method is evaluated for a NACA0012 airfoil and a GLC305 swept wing. In particular, the ability of the approach to simulate horns, feathers and of "lobster tails" or "scallops" is investigated. Numerical tests are performed to assess the accuracy of the proposed method and comparison with experimental data. An improvement in the shapes of ice is seen particularly at icing conditions where feathers are favored in two dimensions, and the lobster tails are expected to appear in three dimensions.
