fluid dynamics - Why are Navier-Stokes equations needed?
Web1. Apart from the experimental and numerical difficulties to track each particle in a macroscopic piece of matter, there are physical reasons. Theoretically, we can show that in the hydrodynamic regime the exact equations of motion for the collection of atoms/molecules reduce to the Navier-Stokes equations. This is shown in statistical … Web22 Nov 2016 · in your equation, you can rewrite it as ∂ ρ u ∂ t and get back to the conservative form. If your problem is that ρ has been extracted from the partial derivation, you can easily put it back inside by manipulating the terms, before any discretization, and obtain the conservative form.
