Finite element thermal analysis of an icing protective system
Abstract
A two-dimensional transient thermal model of an icing protective system is developed using the Galerkin finite element method. The model includes heat transfer by conduction, high-speed convection, evaporation, and fusion as well as the actual ice growth and removal. The program, called FEMTAP, allows for varying heat transfer coefficients, pressure coefficients, and water impingement loads. The de-icer has six heating zones: one temperature controlled and the other five operated by a timer. The heating cycle repeats every 220 seconds. The de-icer is composed of several very thin layers of materials, the total thickness of which is only 0.1256 inches. Results are presented for two different design transients.
