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. WebApr 10, 2024 · For example, the viscous work done by a cross-country skier is calculated as the product of distance travelled and the resisting force (the product of gravitational acceleration, the mass of the skier plus skis, and the coefficient of sliding friction for a given wax, temperature, and snow condition). viscous work
