An analysis of the erosion due to water droplet on a compressor blade 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.

In this work hydroxypropyl methylcellulose (HPMC) fast-dissolving thin films for oral administration are investigated. Furosemide (Class IV of the Biopharmaceutical Classification System) has been used as a model drug for in vitro release tests using three different set-ups: the Franz cell, the millifluidic flow-through device, and the paddle type dissolution apparatus (USP II).
