Abstract

The paper presents numerical heat-transfer correlations established from numerical CFD study of a 3D hotair jet array impinging on curved (circular) surface. The results are in the form of numerical correlations for the average and maximum Nusselt number for different nozzle-to-nozzle spacing, nozzle-to-surface height and hot-air jet mach numbers typical of those in an hot-air anti-icing system employed on aircraft wings. The paper presents a validation case and show that the results obtained from the CFD study are in good agreement with experimental data found in literature. The paper presents an interpolation technique, the dual Kriging method, that make use of the numerical database for anti-icing simulation on aircraft wings. The benefit of using the dual Kriging method is that it preserves the non-linear nature of the heat-transfer distribution from a hot-air jet impinging on a curved surface.
