Název v původním jazyce

High-speed aerodynamics investigation of the midsection of 48´´ Rotorblade for the last stage of steam turbine

Popis výsledku v původním jazyce

A blade cascade representing midspan section of long rotor blading (48") was investigated experimentally in a high-speed aerodynamic wind tunnel and numerically by means of commercial code. In the experimental part, both optical and pneumatic measurements were performed. Measured data were evaluated and different aerodynamic characteristics were obtained. Velocity characteristics determined inlet parameters namely for subsonic regimes and for aerodynamic choking. Exit angle characteristics provided important information about flow parameters downstream of the blade cascade for comparison of design and offdesign conditions. Quality of energy transfer was evaluated from kinetic energy loss coefficient characteristics. Selected results of experiments werecompared to 2D numerical simulations. Discussion based on synthesis of relevant results is mainly concerned with influence of high-speed flow field structures and their development on the performance of the blade cascade and study of flo
