N; PSD Analysis SHOWS that the Front Wall Sub-Cavity Length Ratio of 0.2 Reduces the Dominant Frequency of the Oside The Cavity by NEARLY 60%. IT A lso Reducess The Innsity of the OsCillationsNagpur Stock. The Density Gradient Magnitude Contours Establish that the section shearLayer at the Leading Edge Is Not Affected by the Flow Features Inside the Cavity When the Sub-Cavity is present at the front want. The vortices that Originate at the Edge of the Sub-Cavity. Instead of Reflecting, TheseWAVES DISSIPATE. Hence, The Feedback Loop Gets Disrupted in the Presence of This Sub-Cavity.
A; Increasing the length of the sub-cavity at the front want increases the dominant file, and the shear layer is giveurbed to a great extent by the upstream Eling Pressure Waves.
U; The Numerical Schlieren, shows that when the sub-cavities are present at the afft want, The Pressure Wave Generated Gets DISSIPATED BeFore ReachHing the Leading ED Ge. The Shel Layer Remains Unperturbed by the Wave.The case of all the sub-cavities at the activityBangalore Stock Exchange. EREAS WHEN The Sub-Cavity to Main Cavity Length Ratios Are Between 0.25AND 0.3, The Dominant Frequency is the Fourth Mode, which is more than that of the baseline cavity.
