Finite Volume Method For Cylindrical Coordinates

udhab619 · May 18, 2011, 01:07

I have been assigned the task of discretization of navier stokes equation in cylindrical coordinates in 2-D and writing code for it.please tell me which book or article should I follow to learn the finite volume method easily.

Hi everyone,

I need help, how to get the value of convection coefficient [h] from Fluent directly?
Thank you.

Regrads,

hi
i need c++ code simple algoritm, a cylinder with ro radial and adiabatic. a rod with ri radial insert in sylinder and heat flux is constant,Q"=cost, entree temture and velocity are Tin,Vin , Re=500, outer flow development.
i can not conversion cartezian coordenate to cylinderical coordenate and i do not undrestand boundry condition,

i want calculate veocity profile , friction coefficient on outer surface rod and NU number, i should write program with c++;
please help me
thank you very much.

Hi!
I wrote a 3d code in cylindrical coordinates with FVM.
In staggered gird system, the control cell at the the axis is a triangular cell so that the singularity can be removed.
The only problem is how to calculate the velocity at the axis.
