| Abstract | A morphogenetic model has been developed to predict the ice accretion on an ice sensor resulting from water spray. In the numerical model, the spray is divided into an ensemble of fluid elements and their motion and freezing are considered simultaneously. The model predicts both the ice accretion on the vertical cylindrical surface of the sensor and the accretion below the sensor, including icicle formation. The model also allows the simulation and investigation of the stochastic variability of the accretion shape, something that cannot be achieved with conventional continuous, deterministic models. The model predictions of ice accretion shape and mass have been analyzed as function of water spray mass flux and heat transfer conditions. The prediction of the overall ice structure agrees with a simple heat-balance model and our experimental data. |
