Simulation of an airfoil electro-thermal anti-ice system operating in running wet regime

Abstract

An airfoil electro-thermal anti-ice system operating in a running wet regime was mathematically modeled and simulated. The results were compared to experimental data and results from other numerical codes. For the regions wetted by the water film, the present model predicted airfoil solid surface temperatures within experimental error margin and smaller deviation from experimental data than the other codes. The heat transfer characteristics, runback water flows and water film ending point position were evaluated and compared to other numerical codes results and experimental data. The model predicts satisfactorily the convection heat and mass transfer effects, i.e., wet and dry convection parcels, between the non-isothermal surface and the gaseous flow around the airfoil for engineering purposes as well as the influence of the runback water flow on the anti-ice system thermal performance.
