To distinguish between the different states of fluid flow one must consider how the fluid reacts to a disturbance in the initial state. These disturbances will relate to the initial properties of the system, such as velocity, pressure, and density. James Clerk Maxwell expressed the qualitative concept of stable and … See more In fluid dynamics, hydrodynamic stability is the field which analyses the stability and the onset of instability of fluid flows. The study of hydrodynamic stability aims to find out if a given flow is stable or unstable, and if so, how these … See more Bifurcation theory Bifurcation theory is a useful way to study the stability of a given flow, with the changes that occur in the structure of a given system. Hydrodynamic stability is a series of differential equations and their solutions. A … See more • List of hydrodynamic instabilities • Laminar–turbulent transition • Plasma stability See more Reynolds number A key tool used to determine the stability of a flow is the Reynolds number (Re), first put forward by George Gabriel Stokes at the start of the … See more Kelvin–Helmholtz instability The Kelvin–Helmholtz instability (KHI) is an application of hydrodynamic stability that can be seen in … See more • "Flow instabilities".
