Abstract

There is still little known about the droplet size-erosion rate patterns for wet steam turbine stages. It has been already proved that the structure of the droplet stream may influence very much some of the impact parameters governing the erosion of the turbine blading [1]. In order to shed more light on the problem, a series of experiments was initiated at Institute of Fluid-Flow Machinery. In the test stand of I. F. F. M. the structure of the droplet stream may be readily controlled. The aim of this report is to present the algorithm relating the structure of the droplet stream in the mentioned stand with some impact parameters. Also an attempt is made toward preliminary evaluation of the experimental results presented in [3].
