The influence of the surface properties on the droplets formation
Popis výsledku v původním jazyce
An aim of this paper is introduce an experimental analysis the droplets formation on the surfaces with a different coating. A new wind tunnel was developed for the study of the liquid film atomization for similar conditions in steam turbines. The coarse droplets are formed from the liquid films on the blades and inner casings. The coarse droplets formed on the non-moving blades don't exactly follow the bulk flow and they collide with moving blades. These collisions cause erosion and corrosion processes which have an unfavourable effect on the reliability and the efficiency of steam turbines. The tunnel is equipped with the standard instrumentation for the measurement of the flow properties and for the analysis of the size distribution function of the droplets. Two measurements methods were used for the measurement of the size of the droplets, photogrammetry and light scattering. The paper contains the simple compares of the size distribution functions of the coarse droplets formed on three different surfaces. The first tested surface is not polish stainless steel and two other are the different hydrophobic coatings. The results from the measurement suggest the possibility the control the size distribution function of the coarse droplets by the application of the different coating to reduce the erosion processes in the steam turbine.
