Global measurement approach in characterizing a generic scramjet inlet has enabled the investigation of various flow phenomena typically occurred on an inlet to be investigated further. This paper examines the effectiveness of microvortex generator (MVG) array in suppressing boundary layer separations on such an inlet. Global measurement of pressure and temperature were employed to visualize vortex pairs emanating from the MVG. The global pressure map showed the benefit of lower reattachment peak pressure that usually accompanies the large separation bubble at a scramjet inlet throat.
