WitrynaImpinging velocity Type R. This mode corresponds to low impinging velocities at any surface temperaturesconsidered (200-400 °C). A droplet spreadsas a radial film after impinging on a hot surface. Then, it shrinks and rebounds from the surface without breaking up. Hence, the mode is called R type. [Pg.223] Type H. Witryna1 gru 2011 · The results showed that the highest pure erosion and erosion-corrosion rate was occurred at an impingement angle of 25°. The results also showed that corrosion increased the erosion rate by about...
