Comparative analysis of the results of gas flow in a labyrinth seal for a numerical and theoretical model

Labyrinth seals are an important component of gas and steam turbines design. Many calculation models are available in order to determine the thermodynamic parameters of gas along the seal length: starting with models based on an analytical solution to the problem of gas flow through a seal to numerical models resulting in numerical data and visualizations of conditions inside the seal. In this article the results of calculations made using the Fanno model and the Saint-Venant's Principle with the k-epsilon model in Ansys Fluent are compared.
