WebApplication to the Navier-Stokes Equation. To use the above mechanical model of a numerical instability to understand instabilities that may occur in the Navier-Stokes equation imagine two elements of an Eulerian computational grid in which a perturbation is made to a velocity on the boundary separating two elements, as shown in Fig. 2. Figure 2. WebThe Navier–Stokes equations are based on the assumption that the fluid, at the scale of interest, is a continuum – a continuous substance rather than discrete particles. Another …

WebThis document will consider the compressible ow equations. The compressible Navier-Stokes equations are intimidating partial di erential equations (PDE’s) and rightfully so. … Remark: here, the deviatoric stress tensor is denoted (instead of as it was in the general continuum equations and in the incompressible flow section). The compressible momentum Navier–Stokes equation results from the following assumptions on the Cauchy stress tensor: • the stress is Galilean invariant: it does not depend directly on the flow velocity, but only on spati…
