OBRABOTKAMETALLOV TECHNOLOGY Vol. 24 No. 2 2022 Fig. 7. Mesh model for calculation The computational grid is shown in Figure 7. The minimum and maximum values of a single voxel were set to build the grid: min – 1 mm, max – 5 mm. The same conditions were set for other calculated cases. When modeling, it was assumed that the nozzles would operate at the same pressure and angle relative to the tool axis. For all cases, the pressure was identical and equal to 2.1 kg/cm2 = 0.205 MPa. It is shown that in the processing zone and boundary areas, the grid has taken the minimum values, which should have increased the simulation accuracy. The single-phase oil working fl uid fl ow was modeled using the standard turbulence model (Figure 8). Fig. 8. Calculation construction tree with the fi nal model of the CFXPRE module
