Numerical simulation of airfoil thermal anti-ice operation part 2: Implementation and results

Abstract

This paper presents the implementation and results of the airfoil electrothermal anti-ice mathematical model developed in part l (Silva, G. A. L, Silvares, O. M., Zerbini, E. J. G. J., "Numerical Simulation of Airfoil Thermal Anti-Ice Operation Part 1 : Mathematical Modeling", Journal of Aircraft, submitted for publication). From flow-field and supercooled water droplet impingement data up to electrical power density distribution, the numerical code is able to predict airfoil solid surface temperature and runback water mass flow rate distributions around an airfoil provided with ice protection. The numerical predictions were compared with both experimental data and other numerical codes results for selected reference cases. The present code satisfactorily predicted the coupled convection heat and mass transfer effects between the nonisothermal surface and the gaseous flow around the airfoil, as well as the influence of the runback water flow on the anti-ice system thermal performance.
