Numerical study on nacelle strake mounted on complex high-lift configuration is carried out. Axial and azimuth locations are considered to be the primary factors affecting the flow control performance. A practical design which increases the maximum lift coefficient by 0.3 and the stall angle by 3 degrees is achieved.
