The wavy taper wings configuration showed fascinating result in current studies. The effect of flow properties over a finite wing causes difference performance due to tubercle and also TR Taper Ratio AR Aspect Ratio V Velocity analyzing the influence of flow in wavy profile λ on three dimensional aircraft wings at low velocity. A software analysis was carried out to C change the geometric parameter of the wing with taper ratio and amplitude. The wings were Wavelength In the last few years, the flow control designed by amplitude method and using CATIA. The flow variations results showed that the configurations to be high vulnerable effect of the wavy profile.as it gives to increase in lift co- efficient. The CFD analysis are done by using FLUENT. This analysis is conducted for the models in with and without tubercles. All wing models had a basic NACA0020 airfoil and also consider the tubercle geometry with amplitude of 0.03c and the wavelength of 0.11c. The aim of this analysis is to find the drag and lift force at velocity 30.6m/s for all models and these results are compared with the normal wings. Flow visualization analysis gives better results and to understand the wavy profile effect in the leading edge of the wing.
