Airfoil anti-ice system modeling and simulation

Abstract

An airfoil electro-thermal anti-ice system was simulated with the mathematical model described herein, which is capable to predict temperature and runback water flow streamwise distributions. The results were compared to experimental data and other numerical codes results. For the regions wetted by the water, the present model predicted airfoil solid surface temperatures within the experimental error margin. For the dry regions, the temperature deviations obtained were acceptable and comparable to other numerical codes results. Complementarily, the convection heat transfer coefficient, runback water flow and water film ending point position were predicted and compared to other numerical codes results for both dry and wet airfoil regions. The model predicts the convection heat and mass transfer effects between the non-isothermal surface and the gaseous flow around the airfoil satisfactorily for engineering purposes, as well as the influence of the runback water flow on the anti-ice system thermal performance. © 2003 by the American Institute of Aeronautics and Astronautics, Inc.
