About Navier-Stokes Equations
The Navier-Stokes equations are a set of partial differential equations that describe the motion of viscous fluids.
They are named after the French mathematician and physicist Claude-Louis Navier and the Irish mathematician and physicist George Gabriel Stokes, who developed them in the 19th century.
The Navier-Stokes equations are based on the conservation of mass, momentum, and energy.
They use Newton’s second law of motion (F = m x a) to describe how fluids move.
Importantly, they treat a fluid as a continuous medium rather than tracking individual molecules.
Equation:
The Navier-Stokes equation, in modern notation, is
∂u/∂t + u·∇u = -∇P/ρ + v∇2 u
where u is the fluid velocity vector, P is the fluid pressure, ρ is the fluid density, υ is the kinematic viscosity, and ∇2 is the Laplacian operator.
Navier-Stokes equations have been used to model a wide variety of fluid flows, including the flow of water in pipes, the flow of air around airplanes, and the flow of blood in the human body.
The Navier-Stokes equation is used in a wide variety of applications, including:
Weather forecasting
Climate modeling
Ocean circulation
Aerodynamics
Fluid dynamics
Hydraulics
Lubrication
Combustion
Chemical engineering
Biomedical engineering
There are a number of challenges associated with solving these equations, including:
The equations are nonlinear, which means that they cannot be solved using linear methods.
The equations are coupled, which means that they cannot be solved independently of each other.
Whether smooth solutions in three dimensions continue to exist for all time — the problem of global existence and smoothness — is still an unsolved mathematical question.
Is the Navier-Stokes equation solved?
The Navier-Stokes equation is one of the most important unsolved problems in mathematics.
In 2000, whether smooth, reasonable solutions to the Navier-Stokes equation in three dimensions exist was designated a Millennium Problem, one of seven mathematical problems selected by the Clay Mathematics Institute of Cambridge, Massachusetts, U.S., for a special award.
The solution for each Millennium Problem is worth $1 million.
Despite these challenges, there has been significant progress in solving the Navier-Stokes equations in recent years.
This progress has been due in part to the development of new numerical methods and the use of high-performance computers.
