• ABSTRACT: In this paper, a research was conducted of experimental studies for real blades and CFD modeling of the blades of low pressure steam turbines. To model CFD, developed by solid-state models of blades of a special design are used (with a “back” profile curved against the flow and a thickened outlet edge). The CFD model includes a package of three blades which are similar real blades. Studies are conducted for three gas inlet angles 26, 41, 61. An analysis of the experimental data and the results of CFD modeling of gas flow shows that gratings of a special design have small energy losses at high supersonic speeds. In terms of efficiency, these gratings are superior to traditional gratings by providing continuous flow by large Mach numbers. The use of special grids is rational in the case of turbine operation under variable operating conditions. The developed CFD model can be used as an element in larger models of energy steam turbines.
