EXISTENCE AND SMOOTHNESS OF THE NAVIER–STOKES EQUATION 3 a finite blowup time T, then the velocity (u i(x,t)) 1≤i≤3 becomes unbounded near the blowup time. Other unpleasant things are known to happen at the blowup time T, if T < ∞.
Lecture 2: The Navier-Stokes Equations - Harvard University
projects.iq.harvard.eduLecture 2: The Navier-Stokes Equations September 9, 2015 1 Goal In this lecture we present the Navier-Stokes equations (NSE) of continuum uid mechanics. The traditional approach is to derive teh NSE by applying Newton’s law to a nite volume of uid. This, together with condition of mass conservation, i.e. change of mass per unit time equal mass

math.mit.eduA derivation of the Navier-Stokes equations can be found in [2]. The momentum equations (1) and (2) describe the time evolution of the velocity field (u,v) under inertial and viscous forces. The pressure p is a Lagrange multiplier to satisfy the incompressibility condition (3).
