NettetCFD simulation results generated with coarse grid sizes of 5 cm and 4 cm, as shown in Figure 3, indicate substantial variations from the experimental data; yet the temporal development of normalized scour is improved by reducing the grid size. In order to obtain the most precise results, the grid size is decreased to 2 cm. NettetCFD can be seen as a group of computational methodologies (discussed below) used to solve equations governing fluid flow. In the application of CFD, a critical step is to …
