Default FVM discretization of diffusion term on crvlnr gr

Dear colleagues

I am writing a program for FVM on non-orthogonal curvilinear grids.

I faced a problem with discretization of diffusion term in general transport equation. As example I took M.Peric code and have a his book (Ferziger&Peric, Computatrional methods fo Fluid Dynamics). Also I looked what we have in CFD-Wiki.

But this is not sufficient for understandind and implementation in the program.

I would like to implement deffered correction for non-orthogonal diffusion term.

I'll be very grateful if someone can help me (any link with information or paper - I googled but still haven't found).

i think that sufficient material is available through mentined thesis by john,

but if you look for state of the art and advanced methods, i suggest to look at M. Shashkov publications, he publish couple of papers related to FVM on highly irregular grid (non-orthogonal): http://cnls.lanl.gov/~shashkov/
