The flow of saturated steam through the hole of a submerged perforated sheet (SPS) is analyzed using the FlowVision code. A computational model of one cell of a perforated sheet is created and the grid convergence of the solution on a sequence of refining grids is demonstrated. Four turbulence models including k-eps, k-epsFV, KENL and SST are considered. Comparison of calculated pressure drops with experimental data shows that the SST model gives the most accurate result with an error of less than 3%. The peculiarities of the spatial steam flow through the hole of the SPS have been established. The influence of the degree of perforation on the pressure drop at the hole and the coefficient of hydraulic resistance is analyzed. With an increase in the degree of perforation from 4.3% to 8.1%, the pressure drop decreases by about four times.
