The selected cell depth should be large enough to prevent interference
from the boundary. Here, a height H =5R that suitable for the different
particle velocity is selected, where R is equal to the particle radius.
The cell was simulated by the impingement of rows of identical particles
with a symmetric layout inside each row. These rows are further
combined in series of four rows each. In order to get higher erosion surface
coverage fraction, each subsequent row in the series is caused a
horizontal R movement so that the particles in this row impinge different
areas of the target symmetry cell. The article brings the number of
particle rows to 9. Namely, twenty-two silica particles, represented by
120 μm diameter spheres are fired at the scale, as shown in Fig. 2. In
this paper, the reference includes the contributions made by Meguid
et al. [19] and Zhang et al. [20] of the model.
The eight-noded, 3D solid brick element SOLID164 has been used to
discretize both the substrate and deposited layer. In order to minimize
the computational cost without compromising the accuracy of the
calculations, it is essential to optimize the geometry and the element
size of the erosion domain. Hence, Mesh refinement is adopted to the
coating and the interface where the coating combined with substrate.
All particles are identically meshed using eight-noded brick element
