Abstract
This paper presents an experimental study of geometric and cinematic characterization of an impinging spray of a low-pressure gasoline injector. Spray impingement process was analyzed using an experimental set up that is capable to elaborate spray images gathered in different time steps before and after the impact.
The results are expressed in terms of impact velocity, spray morphology and radial and axial evolution of the jet, as a function of characteristic parameters such as injector-wall distance and impact angle.
The results provide useful information for both better understanding of the impinging of a jet on a solid wall, and the validation of physical models to be implemented in a CFD code, in order to obtain more reliable simulations of the injection process.
