WebThe jet forms near a rotating disk, goes to the inte rface near the sidewall, and converges to the axis near the interface. New circulatory cells emerge in both ﬂuids and the interface signiﬁcantly bends. The instability develops after such ﬂow pattern becomes well formed. The instability focuses near the interface where the jet-like WebThe Rayleigh-Plateau instability is defined by two factors: the growth rate of the perturbations and length scale over which the instability grows. In this system, the time …
