Numerical and experimental aerodynamic investigation of small-sized impulse-type turbine stage
Straka P., Němec M.
pages 389 - 392, full text

Numerical and experimental investigation of flow in a small-sized axial turbine stage of impulse type was carried out in order to determine the aerodynamic and energy parameters. Special attention was paid to over-loaded regimes with negative value of the thermodynamic reaction. This study pointed on a strong effect of a leakage flow from a hub labyrinth seal on the stage efficiency. Numerical simulation allowed to study a development of a secondary flow structures in peripheral parts of a blade span. In this paper there are compared results of numerical simulations and experimental investigation.
