Comment Section for Navier–Stokes equations - Wikipedia

The webpage discusses the Navier-Stokes equations, which are partial differential equations used to describe the motion of viscous fluids. These equations mathematically express momentum balance for Newtonian fluids and take into account factors such as viscosity and pressure. The webpage explains the general continuum equations and describes specific subsections, including compressible and incompressible flow, non-inertial frame of reference, stream function for incompressible 2D fluid, and properties of the equations such as nonlinearity and turbulence. It also mentions the applicability of the equations to various fluid flow problems and the challenges in solving them, particularly in turbulent flow situations.
