“…In the literature a lot of publications and papers are dedicated to water film removal from the blade surfaces (Gribin et al (2010), Sakamoto et al (1992), Tanuma and Sakamoto (1991)). But as shown by recent investigations (Gribin et al (2016) and Hoznedl et al (2012)) the number of removed water is strongly dependent on the operational parameters of turbine. Even small changes in turbine stage operational conditions reduce the efficiency of this method.…”

“…The methodology of laser diagnostic system adapted to the polydisperse wet-steam flow. This is successfully applied in Gavrilov et al 2014, , Filippov et al (2014), Gribin et al (2016) and Gribin et al (2014). The steam velocity (c s ) was determined by a simulation using the Ansys Fluent 14 incorporating wet-steam model.…”

The results of the experimental studies of wet-steam flow with injection of hot steam from the slot downstream of the turbine flat stator blade cascade have been considered. In the studied profile there is one injection slot on the pressure side surface near the trailing edge. The investigations have been carried out at different initial wetness of the main flow and different injected steam temperatures at the constant pressure of injection. Laser diagnostic system "POLIS" which includes PIV method has been used to analyze the influence of heating steam injection on the characteristics of the liquid phase downstream of the blade trailing edge. It is shown a heating steam injection has an effect on the vector fields of coarse droplets downstream of the blade cascade. At the same time kinetic characteristics of coarse droplets downstream of the stator blades cascade are independent of the temperature of the injected steam. Exit angles of coarse droplets obtained at the different distance from the trailing edge are presented.
