For the original Navier-Stokes problem we construct next global solution of the Leray-Hopf type satisfying also Duhamel's integral formula. Focusing finally on the 3-D model with zero external force we estimate a time after which the latter solution regularizes to strong solution.

We also estimate a time such that if a local strong solution exists until that time, then it exists for ever. Google Scholar.

Second, we also wish to retrieve the classical spectral convergence properties of spectral methods.
Note spectral convergence as N increases. The analytic reference solution is not shown here, at it is indistinguishable from the SEM solution. The black fit line corresponds to an exponent of 1.

Motion is generated inside the tangent cylinder only, as the fluid located outside is insensitive to the super rotation by virtue of the Taylor—Proudman theorem. A shear layer is created along to accommodate the shear between the two regions. On the left contour plots of the meridional stream function are shown, while the right shows contour plots of the angular velocity.
Note the transition from a smooth, essentially viscous solution b to a solution dominated by rotation d. This classic kinematic flow problem in its asymptotic form was originally proposed by Proudman It was developed later by Stewarston , , who derived the exact structure of the shear layers alongside of. Since then it has been treated numerically by several groups Hollerbach ; Dormy et al. Its linear character, moreover, makes it an ideal test case to verify the numerical accuracy of our method, leaving aside complications that inevitably appear when one introduces non-linear effects.
First, we describe the reference numerical solution together with the changes in the physics of the solution, as we go from a slowly rotating system to a system rotating more rapidly. Our numerical reference solution is the spectral solution published by Hollerbach It is displayed in Fig.
