| Summary: | The icing accumulation on the aircraft wings is a one of dangerous problem that change the wing profile, reduce the aerodynamic performance, and finally it can lead to a very major accidents during flight. The system of Anti-Icing is a significant system that is used to avoid these phenomena using hot airflow bleeding from the engine compressor. This research aims to analyse the effect of Anti-Icing geometric parameters on the system performance using computational investigation. A partial-span model (PSM) was constructed from NACA-23014 airfoil and the numerical domains were created and solved by ANSYS software for different geometric parameters. The effect of jets organization, impingement angles (α), and horizontal distance (H) between the wing inner surface and piccolo-tube on the thermal performance of aircraft wing are investigated at constant mass flow rate. The contours of thermal parameters were predicted for every case and compared to evaluate the improvement percentage. The results illustrate that, the heating performance of Anti-Icing system will be more effective when the hot jets were used with double staggered organization at H = 9.01 mm which gives a satisfactory distribution of the temperature on wing surfaces, also the system effectiveness will improve with increasing the impingement angles of hot jets. |
