WebNov 1, 2024 · The Rayleigh–Taylor instability (RTI) and internal waves in both the incompressible and compressible dense degenerate strongly coupled quantum plasma have been investigated considering isothermal ion fluid compressibility. The quantum hydrodynamic model is formulated considering weakly coupled degenerate electrons and … WebInterfacial fluid mixing driven by an external acceleration or a shock wave are common phenomena known as Rayleigh–Taylor instability and Richtmyer–Meshkov instability, respectively. The most significant feature of these instabilities is the penetrations of heavy (light) fluid into light (heavy) fluid known as spikes (bubbles).
