In the case of compressible flow, due to the gravitational field, the source term added in the momentum equation (which is gravitational potential) is $Gm/r$ in the case of cylindrical geometry and $Gm/r^2$ in the case of spherical geometry. So my question is how does it come in the case of cylindrical geometry? What would be Poisson's equation for cylindrical geometry?

  • $\begingroup$ No. The fluid flow is taking inside a cylinder which is axisymmetric. $\endgroup$ – Sumeeta Jul 16 at 6:22
