grid convergence study.
Meshes refining was carried out according to the
grid convergence index suggested by Longest and Vinchurkar [14].
Meshing and Evaluation of
Grid Convergence. The examination of the
grid convergence was performed considering the flow rate of 1.0 kg/s at exit, with 5.8 mm gap width and a fine meshing of 8.8 million elements and a range of course meshing whose grids are 4.1 million, 1.8 million, and 0.75 million elements.
In order to verify the accuracy of the numerical model, the
grid convergence index (GCI) (Celik et al., 2008) was selected to test the uncertainty in the numerical results with different grid sizes.
In reality,
grid convergence is achieved at larger grid sizes due to numerical dissipation.
[5] did a
grid convergence study for LES spray using the CONVERGE code [6,7].
