There are a number of C/C++ libraries to help with map projection at MapTools if you need to reproject your distances to a flat surface. To do this you will need the projection string of the various coordinate systems. You may also find MapWindow a useful tool to visualise the points.In Cartesian coordinates with the components of the velocity vector given by , the continuity equation is (14) and the Navier-Stokes equations are given by (15) (16) (17) In cylindrical coordinates with the components of the velocity vector given by , the continuity equation is (18) equation, the isothermal drift-diffusion equations, and higher order moment equations derived from the Boltzmann transport equation for general coordinate systems. We brieﬂy summarize the method of dimension reduction when the problem does not depend on one coordinate. Discretization schemes for dimension-reduced coordinate systems are ...

Fundamental Theorems: Vorticity and Circulation 7.1 Vorticity and the equations of motion. In principle, the equations of motion we have painstakingly derived in the first 6 chapters are sufficient unto themselves to solve any particular problem in fluid mechanics.

A novel procedure, developed for transforming equations into general orthogonal coordinates, has been used to obtain the transport equations for velocity and a general scalar yf = D⇣ Dt +v (8.42) Thus, the left-hand-side of the evolution equation of vorticity can be written as D Dt (⇣+f)= @⇣ @t +v·r⇣+v (8.43) The ﬁnal term v appears because the Coriolis parameter varies with latitude.
