NUMERICAL SIMULATION OF DE-ICING AND ICE SHEDDING ON MULTILAYERED STRUCTURES
Electro-thermal de-icing problems occurring in multilayered structures covered with ice was numerically modeled. The enthalpy method was applied to solve transient heat transfer equations with the phase change between ice and water. Assumed phase state for each node was used to linearize the equations such that a direct solution is possible. Numerical results are presented to compare the present code simulations to some data provided by other de-ice prediction codes and to show the capabilities of the present numerical tool. Ice shedding model based on bonding strength was developed. The ice shedding time and temperature distribution after shedding were simulated and analyzed.
