Numerical simulation on the effect of vortex generator on unsteady aerodynamics of cylindrical protrusion was studied. All simulation were carried out at Mach number 2.0 and the Reynolds number 3.6×10⁷/m. Three dimensional steady and unsteady LES simulation is carried out. The flow field properties around the cylindrical protrusion from the present numerical results is compared with the existing experimental result for steady pressure data. Good agreement between the numerical and experimental result has been achieved. Use of vortex generator shows reduction of peak pressure acting on the cylindrical protrusion. The comparison of power spectral density for cylindrical protrusion with VG is obtained which clearly indicates that the high frequency power spectra can be reduced and also helps in reduction of pressure drag acting on the cylinder.
