Web15 de abr. de 2015 · The Navier-Stokes equations, written in conservative vector form, are. ∂ ρ u ∂ t = − ∇ ⋅ u ρ u – ∇ ⋅ τ – ∇ p. I always liked to use this form of the Navier-Stokes equations. I think it is simple and convenient. But, today I realized that it could easily lead to trouble, specifically when interpreting the convective term. Remark: here, the deviatoric stress tensor is denoted (instead of as it was in the general continuum equations and in the incompressible flow section).
