CFD analysis of fluid flow through the labyrinth seal

Abstrakt

Steam and gas turbines are some of the fundamental means of power generation. The energy efficiency of the turbines, however, is not satisfactory. Ever since the start-up of the first turbine in the world, engineers have been striving for their increased efficiency. Multiple solutions to the problem of steam loss in an operating turbine are available. The use of seals is one of them. Empirical methods or numerical calculations may be used for determining the thermodynamic parameters of steam in a seal. Empirical tests are excessively expensive and time-consuming. Therefore, computational fluid dynamics (CFD) is gaining popularity in the analysis of a liquid flow through a labyrinth seal. This article describes the results of calculations made in Ansys Fluent using its k epsilon calculation model.
