Heat and Mass Transfer in the Case of Anti-Icing System Simulation

Abstract

Aircraft manufacturers need anti-icing system simulations to help in the design of ice protection systems. Heat and mass transfer predictions obtained with two different methods to solve the boundary layer in the case of an anti-icing simulation are compared. The integral method and the finite difference method are used to solve the boundary-layer equations, including the mass diffusion equation. The boundary-layer solvers are implemented into the code CANICE, which models the ice accretion process. Comparison of heat and mass transfer distributions and surface temperature distributions are made. Surface temperatures predicted with the finite difference method are closer to experimental results than surface temperatures predicted with the integral method
