Numerical Simulation of Unsteady Conjugate Heat Transfer of Electrothermal Deicing Process

Numerical Simulation of Unsteady Conjugate Heat Transfer of Electrothermal Deicing Process

A novel 3-D unsteady model of in-flight electrothermal deicing process is presented in this paper to simulate the conjugate mass and heat transfer phenomena of water film runback, phase change, and solid heat conduction. Mathematical models of water film runback and phase change are established and...
