Caractérisation expérimentale des jets d'injection diesel à très hautes pressions (2500 bar)

Abstract : Thesis work has permitted to obtain, experimentally, the geometric features of Diesel free sprays for injection pressures not unreached so far (2500 bar). Those features have been obtained thanks to a specific test bench and via a picture processing software development. They have enabled us to evaluate the influence of such pressure on pulverization quality. This study has permitted to enlarge , for higher pressure, the application field of laws already suggested by somes authors. It has also enabled us to obtain new temporal evolution laws able to inform phenomenologic combustion models. Nevertheless, an energizing study of pressure generation has shown that we should be very cautious as to the interest of the injection pressure increase.
