The radial component of eq:aniso:scalar:nse. Take the momentum equation at i = 0 from
hsol.2.2.2.1 z hz 0, rewrite its convective sum with
sum_convective_zero_meridional and its Laplacian sum with
sum_spatialSecondPartial_zero_meridional, and rearrange. The centrifugal
term -u_θ²/r comes from the convective rewrite and the -u_r/r² from the Laplacian rewrite.
