Unstructured grid finite volume methods

Marcus

I'm aware of the fact that unstructured finite volume methods for CFD computations can be developed by defining field quantity (velocity, pressure etc)variations across a finite element type grid and then overlaying this grid with a dual grid of control volumes such that volume 'centres' and element vertices coincide. The discrete equations are then obtained by satisfying the relevant conservation principles across the volumes.

I'm keen to find out more details of this type of approach. To help me out can anybody point me towards some of the pertinent references in the journal literature.

Thanks
