An analysis of the erosion due to water droplet on a compressor blades case is performed. The study reports the erosion patterns due to droplets of 15 μm diameter dragged by the main flow. An analysis of the droplets dynamics and erosion patterns is provided. The study put in evidence the influence of the tip leakage vortex and the separation close to the hub on the droplet motion and erosion patterns.
Blade fouling is a very relevant problem in turbomachin-ery applications. It affects both compressors and turbines. In the first case, fouling can be generated by the presence of dust, ashes or brackish air (in offshore applications). In turbines, fouling is mainly generated by residual of combustion process. Blade fouling generally leads to a reduction of the performance due to an increase on profile losses. Here we focus on the foul-ing due to salt deposition on naval/off-shore applications refer-ring to machines that are part of the fleet of gas turbines man-ufacturers.
