Abstract
The aim of the study is to numerically simulate the flow of steam/steam-water mixture through one periodic cell of a submerged perforated sheet, which is an important element of the separation scheme of a horizontal steam generator. The OpenFOAM code is used as a calculation tool. First, the flow of single-phase steam was considered. A comparison of the values of pressure drops on the perforated sheet obtained using the OpenFOAM code for two turbulence models with pressure drops determined by other CFD code FlowVision, various approximate formulas and experimental data shows that the variation of all values does not exceed 10%. The influence of a liquid film on the flow of steam through the hole and the resulting pressure drop is investigated. It is shown that the water film reduces the pressure drop on the perforated sheet by about 6% compared with the flow of single-phase steam.
