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 < ∞.

www.whoi.eduThe Stress Tensor for a Fluid and the Navier Stokes Equations 3.1 Putting the stress tensor in diagonal form A key step in formulating the equations of motion for a fluid requires specifying the stress tensor in terms of the properties of the flow, in particular the velocity field, so that
A Practical Introduction to the Lattice Boltzmann Method
www.ndsu.eduNavier Stokes equations and it was shown that the lattice gas methods could be used to simulate (rather noisy) hydrodynamics. However, the lattice gas methods had several drawbacks consisting mainly of their noisy nature and the apperance of some additional terms in the Navier Stokes level equations that limited their success.

www.dgp.toronto.eduthe air.The Navier-Stokes Equations are a precise description of the evolution of a velocity field over time. Given the current state of the velocity and a current set of forces, the equations tell us precisely how the velocity will change over an infinitesimal time step. Figure 1 (top) depicts these equations in a compact vector-like notation.

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).
Navier-Stokes Equation: Principle of Conservation of …
web2.clarkson.eduthe Navier-Stokes equation is derived. The principle of conservation of momentum is applied to a fixed volume of arbitrary shape in space that contains fluid. This volume is called a “Control Volume.” Fluid is permitted to enter or leave the control volume. A control volume . V is shown in the sketch. Also marked on the sketch is the ...
