In this study, anti-icing problems, which are mostly industrial problems in aerospace companies, have been numerically investigated. Herein, to enhance anti-icing performance of NACA0015, different jet-to-surface distances (H/d), jet angles (α), and slot jet designs with different aspect ratios (ARs) have also been investigated. ANSYS Fluent 2020R2 commercial program has been utilized for all numerical calculations. In addition, the SST k-ω with low-Re correction wall treatment turbulence model has been used for solving turbulence equation. Furthermore, the average Nusselt number (Nu) on the NACA0015's surface, pressure drop, and performance evaluation criteria (PEC) which define the anti-icing performance of novel proposed system have been presented section by section. As a result of the investigation, it has been obtained that the use of AR = 4 increases the Nu by 85.52% compared to circular jet for the H/d = 4 at α = 90°. The pressure drop value dramatically increases using AR = 4 around 307.85% compared to circular jet for H/d = 4 at α = 90°. Despite this drastic increment in pressure drop, the PEC value is kept as 1.14 using AR = 4, H/d = 4, and α = 90°. Finally, empirical correlations developed from existing findings have been presented with an error rate of lower than 5%.
