Numerical Simulation of Electro-thermal Deicing Process

摘要：

A code was developed to numerically simulate an electro-thermal deicing system. The deicing process was an unsteady heat transfer process including phase change. Phase change was performed by an enthalpy method. A staircase approach was used to simulate the variable ice layer thicknesses. The control volume method was adopted to discretize the governing equations. The Tri-diagonai matrix method, alternating direction implicit method and block-correction technique were used to solve the discrete equations. The comparison of temperature with previous studies showed good agreements. The results of a case were analyzed.
