I need to solve Navier-Stokes equation in spherical coordinate. Prof. Batchelor gave mass and momentum equations directly without derivation in his book "An introduction to Fluid Mechanics", 1967. Besides, some show a coordinate transformation from Cartesian, which is not clear from a physical basi...
the global strong solution in time to the three-dimensional incompressible Navier–Stokes equations, we prove that there exists the unique and global strong solution to the Cauchy problem for the three-dimensional incompressible Euler equation without swirl in spherical coordinates with large initial ...

H.-O. Bae and H.J. Choe, in a 1997 paper, established a regularity criteria for the incompressible Navier-Stokes equations in the whole space ℝ 3 based on two velocity components. Recently, one of the present authors extended this result to the half-s
In spherical coordinates with the components of the velocity vector given by , the continuity equation is (22) and the Navier-Stokes equations are given by (23) (24) (25) The Navier-Stokes equations with no body force (i.e., )
The particular solutions are themselves solutions of the Stokes non-homogeneous system of equations, with multiquadric (MQ) radial basis function used as the source term. In the proposed numerical scheme, the continuity equation is not explicitly imposed, since the particular solutions used exactly ...
