Abstract
Numerical and experimental analyses of hollow cone sprays generated by pressure-swirl injectors for Direct Injection Spark Ignition (DISI) engines have been performed.
Spray characteristics have been measured by a gathering and processing system for spray images, including a CCD camera, a frame grabber and a pulsed sheet obtained by the second harmonic of Nd-YAG laser (wavelength 532 nm, width 12 ns, thickness 100 μm).
A detailed spatial and temporal characterization of the emerging spray has been carried out showing interesting peculiarities of the jet for different operative conditions.
Some results of a work in progress, aiming to select and to validate proper models for the spray development simulation are, also, discussed.
Numerical calculations are based on the KIVA 3V code modified in basic spray sub models.
Some important physical phenomena are captured in the computations at the backpressure of 0.1 MPa.
Moreover, the model seems to simulate correctly different type of injectors.
On the contrary, the proposed numerical procedure doesn't seem to predict correctly the spray motion at increasing backpressure.
