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 instabilities will cause the development of turbulence. The foundations of hydrodynamic … See more 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 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. … See more • List of hydrodynamic instabilities • Laminar–turbulent transition • Plasma stability • Squire's theorem • Taylor–Couette flow 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".
