Web2 de ago. de 2024 · The instability focuses near the interface where the jet-like motion approaches a new cell, decelerates, and diverges—hence the deceleration and shear-layer effects work together. In oil–water flows, the instability develops in the lower fluid, either in its depth or near the interface depending on the water volume fraction.
