What is it about?
In this work, we analyze how angled turbulent jets interact with cylinders. We show that oblique momentum injection elongates the wake and suppresses vortex shedding frequencies, demonstrating that vertical slits stabilize the wake via a penetrating jet core while horizontal slits induce highly unsteady, multi-modal modulation.

Why is it important?
These results identify slit orientation and oblique forcing as coupled frequency-selection mechanisms, offering new insight into wake control under non-orthogonal momentum injection and informing future extensions to vibration mitigation, magnetohydrodynamic modulation, and heat-transfer enhancement.
Perspectives
By examining the interplay between slit geometry, impingement angle, and Reynolds number, this work provides new physical insight into passive wake manipulation in jet– cylinder systems and identifies mechanisms for controlling shear-layer coherence, wake recovery, and turbulence production.
