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...
Rotating spherical coordinatesWe show that a consistent shallow-water approximation of the incompressible Navier-Stokes equation written in a spherical, rotating coordinate system produces, at leading order in a suitable limiting process, a general linear theory for wind-induced ocean currents which goes...

An exact solution to the Stokes equation is obtained in oblate spherical coordinates. The results show that a radial incoming flow induced upstream of the hole moves almost parallel to the hole in its vicinity, and then is reflected into a radial outgoing flow...
The incompressible Euler or Navier–Stokes (Euler/NS) equations in d space dimensions can be written as (1.1)∂u∂t=−L(u•∂u)+νΔu+f, where: u=u(x,t) is the divergence free velocity field; x=(xs)s=1,…,d are the space coordinates (yielding the derivatives ≔∂s...

Proof of Proposition 5.1: Equation (5.1) can be written in the integral form using the heat kernel Γ and the Stokes tensor (2.55), w = wL + wN (w), (5.13) where wL = et∆w0, wL(t, x) = Γ(t, y)w0,i(x − y)dy, (5.14) t wN (w)(t, x) = − ∂kSij(s, ...
