The effect of corrugation on the mixing promoting performance of a limiting tab will be assessed by studying the decay of a jet emerging from a convergent-divergent nozzle, with a limiting tab, with and without corrugation, running along a diameter at the nozzle exit, operated at certain nozzle pressure ratios. Uncontrolled jet was also will be studied for comparison. The physics behind the difference between the mixing caused by the uncorrugated and corrugated tabs in the presence of adverse and favourable pressure gradient will be addressed using the density gradient contours of the jet core as the main source and the centerline Mach number decay as the supporting material. Unsteady Reynolds averaged Navier stokes equation will be solved using Ansys CFX tool.The physics behind the difference between the mixing caused by the uncorrugated and corrugated tabs in the presence of adverse and favorable pressure gradient is addressed using the shadowgraph images of the jet core as the main source and the centerline pitot pressure decay as the supporting material. The results show that the mixing promotion caused by the tabs leads to the shortening of the third and fourth shock cells in the jet core. This can be regarded as an advantage from the screech suppression point of view.
