On the Divergence-Form Finite-Difference Approximation to the Momentum Advection in Curvilinear Orthogonal Coordinates
The traditional finite-difference schemes for the dynamical equations in curvilinear orthogonal coordinates have a basic flaw: they conserve only energy, but not momentum. A finite-difference approximation to these equations is suggested that conserves both energy and momentum. (C) 2000 Elsevier Science Ltd. All rights reserved.
