Derivation of Differential Fluid Equations - ShouRou

WebIn fluid mechanics, the Navier-Stokes equations are partial differential equations that express the flow of viscous fluids. These equations are generalisations of the equations developed by Leonhard Euler (18th century) to explain the flow of frictionless and incompressible fluids. WebThe term ( ⃗ ) ⃗ on the right hand side is known as the convective term. It is the term which makes the Navier-Stokes equation nonlinear. ⃗ is known as the viscous term or the diffusion term. For diffusion dominated flows the convective term can be dropped and the simplified equation is called the Stokes equation, which is linear.
