Abstract

In the following text attention is given especially to the scope of problems relating to a three-dimensional flow of the steam phase, wherever possible under all working conditions of the turbine, from an idle run to the full output. Some secondary effects caused by the flow under working regimes departing from the design are considered too. 

The experiments presented in the following relate mostly to the low-pressure section with last stage having blades of 840 mm length. For the arrangement of this section for a turbine of 500 MW see Fig. 1. Steam is admitted from above by two pipings and passes from the last stages down to a condenser, which is placed under the turbine.
