Hydrodynamic instabilities refer to phenomena in fluid dynamics where a steady flow becomes unstable, leading to the development of unpredictable and chaotic flow patterns. Several of these instabilities are named after researchers who played significant roles in their discovery or theoretical development. Here is a list of some notable hydrodynamic instabilities named after people: 1. **Rayleigh-Bénard Instability**: Describes the convection patterns in a fluid layer heated from below.

Two-stream instability is a phenomenon observed in plasma physics and astrophysics that occurs when two streams of charged particles (such as electrons or ions) move parallel to each other but with different velocities. This situation is common in various astrophysical and laboratory plasmas, where the behavior of charged particles is influenced by electromagnetic forces.

The Saha ionization equation is a mathematical formula that describes the ratio of the number densities of ions to neutral atoms in a thermal equilibrium state, particularly in astrophysical contexts such as stellar atmospheres. It is useful for understanding how ionization states of elements vary with temperature and electron pressure.

Shear rate is a measure of the rate at which one layer of a fluid moves in relation to another layer. It is a critical concept in fluid dynamics and rheology, particularly for non-Newtonian fluids, where the viscosity (resistance to flow) can vary with shear rate. Mathematically, shear rate (\( \dot{\gamma} \)) is defined as the change in velocity (speed) of a fluid layer divided by the distance between the layers.

A gridded ion thruster is a type of electric propulsion system used primarily in spacecraft for propulsion and maneuvering in space. It works by using electric fields to accelerate ions, which are charged particles. The primary components of a gridded ion thruster include: 1. **Ionizer**: A gas (usually a noble gas such as xenon) is ionized by electron bombardment, creating positive ions and free electrons.

Non-neutral plasma refers to a type of plasma that has an imbalance in the number of positive ions and negative electrons, leading to a net electric charge. In contrast, a neutral plasma typically contains equal amounts of positive and negative charges, which results in a net charge of zero. In non-neutral plasmas, the excess of one type of charge can create electric fields and potential gradients that affect the dynamics and behavior of the plasma.
