The validation of 3D CFD models for the simulation of the in-cylinder thermo-fluidynamic processes underlying energy conversion is performed through a detailed experimental insight into the dynamics and impact over walls of multi-hole sprays for DISI applications through combined schlieren and Mie scattering techniques. Experimental tests aimed at collecting detailed information about spray impact against hot walls and the consequent complex heat transfer were performed in a constant volume combustion vessel optically accessible by three quartz windows allowing the admittance to the investigated area.

Abstract
The validation of 3D CFD models for the simulation of the in-cylinder thermo-fluidynamic processes underlying energy conversion is performed through a detailed experimental insight into the dynamics and impact over walls of multi-hole sprays for DISI applications through combined schlieren and Mie scattering techniques. Experimental tests aimed at collecting detailed information about spray impact against hot walls and the consequent complex heat transfer were performed in a constant volume combustion vessel optically accessible by three quartz windows allowing the admittance to the investigated area.File in questo prodotto:
