| dc.description.abstract | In the low pressure section of the steam turbines the damages due to the
erosion are pronounced becoming remarkable in all the stages, since the
generation of water liquid microparticles implies the impact on the blades having
majors problems of erosion in the last stages by the increase of the humidity.
The methodology of calculation of the velocity and pressure distribution on
the basis of the frictionless, two-dimensional, stationary, transonic and
homogenous flow is established. The knowledge of conditions that govern the
low pressure section of steam turbines in the last stage to have an approximate
movement of the droplets in the blade cascades and the accumulation of
droplets on the stator blades, flowing through the steam, is presented.
This study is used for developing a code in Fortran about the pressure and
velocity and pressure distribution in the output of stator blades that have flow
conditions of wet steam, in order to understand the causes that originate the
erosion on the blades of the last stages in the low pressure section of steam
turbines. | |
