Steam and gas turbines are essential to produce electricity. Since the launch of the first turbine in the world, there become a tendency to constantly achieve higher efficiency. There are many solutions to overcome losses in the working steam turbine. One of such methods is the use of seals. To determine thermodynamic parameters of steam, which prevail in the seal, we could use experimental methods or numerical calculations. Experimental researchs are too expensive and time consuming. Therefore, computational fluid dynamics (CFD) is increasingly used in the analysis of fluid flow through the labyrinth seal. The paper describes the results using CFD simulation software with the help of contained a computational k-ε model.
