Abstract

Swirl represents a form of energy loss, as the energy is used in accelerating the flow in the angular direction and does not contribute to engine thrust. Significant swirl flow in resulting in the fighter aircraft intakes during manoeuvres can result in an undesirable engine performance. The CFD study conducted using FLUENT shows that the F-5E intake is more sensitive to the negative angles of attack, especially for AOA at −10°, where bulk swirls were seen forming. In the results of Taguchi and ANOVA, both statistical model point to the angle of attack play the most significant role in determining a more undesirable swirl coefficient.
