Conservatism of the grid convergence index in finite volume computations on steady-state fluid flow and heat transfer

Some observations which were relevant to the evaluation of the adequacy of the conservatism of the grid convergence index (GCI) method of uniform reporting of grid convergence studies for verification of calculations were shown. As such, a uniquely far-ranging applicationof the GCI were given. This paper reports on the results obtained from the examination which shed light on the question of the conservative (or nonconservative) character of the GCI in the engineering sense.
