Oblique spray impingement onto rigid walls: description of secondary spray

In this work, an experimental study of oblique spray impact onto a flat and rigid surface is presented. A phase Doppler instrument has been used to measure drop size and two components of velocity directly above the target. Characterization of spray-wall interaction, including velocity and trajectory of secondary droplets also mass and number ratio of secondary spray has been performed. An interesting feature of these experiments is the rather large oblique impact conditions due to the different injection angles exiting from the pressure nozzle. In this paper some new features of oblique spray- wall interaction will be presented.
