Hydrodynamic instabilities such as Rayleigh–Taylor (RT) and Richtmyer–Meshkov (RM) usually appear in conjunction with the Kelvin–Helmholtz (KH) instability are found many natural phenomena engineering applications. They frequently result turbulent mixing, which has a major impact on overall flow development other effective material properties. This can either be desired outcome, an unwelcome si...

Hydrodynamic instabilities in one-dimensional electron flow in semiconductor and their dependency with the electron and lattice temperatures are studied here. The driving force for the electrons is imposed by a voltage difference, and the hydrodynamic and electrostatic equations are linearized with respect to the steady-flow solution. A two-temperature hydrodynamic model predicts a stable elect...

We present results of an experimental study on the stability of Taylor–Couette flow in case of counter-rotating cylinders and an imposed axial through flow. We are able to confirm results form recent numerical investigations done by Pinter et al. [24] by measuring the absolute and convective stability boundaries of both propagating Taylor vortices (PTV) and spiral vortices (SPI). Thus our work ...

Studies on small-scale jets’ formation, propagation, evolution, and role, such as type I II spicules, mottles, fibrils in the lower solar atmosphere’s energetic balance, have progressed tremendously thanks to combination of detailed observations sophisticated mathematical modelling. This review provides a survey current understanding jets, their formation atmosphere, evolution from observationa...
