 October 7, 2004, 11:27 Divergence theorem in cylinderical coordinates #1 peter.zhao Guest   Posts: n/a It's common for finite volume method to calculate the derivatives in viscous flux according to divergence theorem, but I do not known the detail formula in axisymmetrical cylinderical coordinates. for example, how to caluclate the derivatives of temperature according to divergence theorem? Thank a lot in advance!

This shows all the vector operations in the three major coordinate systems - along with lots of other details. A bit less expensive, Schwamm's outline series has a soft-cover summary on Vector Analysis.

Can you shed light on it?

Amsden, and J. L. Cook, "An arbitrary Langrangian-Eulerian Computing Method for All Flow Speeds," J. Comp. Phys, v. 14, pp. 227-253 (1974). Also the reports for the KIVA series of codes developed at Los Alamos - if you can get them. Finally, try the U. of Wisconsin web sites for research simulating combustion in a diesel engine that was spun off from the KIVA-series codes. I don't have the details readily available. You might try contacting Hans Ruppel at Los Alamos, who at one time had a nice set of notes working out the details of the surface integral around a control volume. Good luck!
