Abstract
In the article carried out investigations of the gas flows in the labyrinth seals. Also aerodynamic forces arising in steady-state rotating rotor were calculated using commercial CFD ANSYS-CFX. Different labyrinth seal models were investigated - model with a given clearance (uniform) and model with an eccentricity. For these cases were obtain results for gas flows in the steady-state conditions leaking through seals with different eccentricities. The article is useful for engineers specialized in aerodynamics and turbo-machinery.Keywords:
