In this study, we apply an incremental pressure correction scheme to a coupled Navier-Stokes-Darcy problem in order to model porous and viscous flow in and around the human spinal cord. Simulations show that the central canal, a narrow channel in the spinal cord which is usually only partly present in most adults, has a profound effect on pressure distributions within the spinal cord - an effect that can be of importance in the study of cyst formation in the cord. The numerical method was verified using the method of manufactured solutions, showing that the simple operator splitting scheme produces reliable results in this complex case.
