Experimental research on steam flow through a two-stage turbine is presented. Change of pressure and velocity ratio in individual stages is studied. The effect of the Reynolds number and the Mach number on the thermodynamic efficiency of individual stages as well as the entire turbine is evaluated. Steam flows through the blades and steam leakages through the shroud sealing and the shaft sealing are described.
