WebThe critical Rayleigh number for linear stability ${Ra}_L$ has different behaviour in the small and large $\omega$ limits. Below a certain value of $\omega$ , the critical Rayleigh number arises alternately from synchronous and subharmonic disturbances, and decreases non-monotonically as $\omega$ decreases. WebApr 14, 2024 · The acceleration of ultrathin targets driven by intense laser pulses induces Rayleigh–Taylor-like instability. Apart from laser and target configurations, we find that electron heating and surface rippling, effects inherent to the interaction process, have an important role in instability evolution and growth. green valley hs football https://superior-scaffolding-services.com
