Vehicle configuration Cell count V1 35 million V2 86 million V3 59 million TABLE 3 Summary of grid convergence
Meshes refining was carried out according to the grid convergence
index suggested by Longest and Vinchurkar .
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.
 did a grid convergence
study for LES spray using the CONVERGE code [6,7].
