摘要：
The contribution deals with numerical modelling of flow through a simplified shaft labyrinth seal for various operating regimes. The objective is to obtain dependency of the mass flow rate through the seal and the outlet flow angle from the seal on the pressure ratio and the rotation. The results will be used as a background for modification of the test-rig for axial turbine stage.
