CHARACTERISTICS OF ADHESION DIESEL FUEL ON AN IMPINGEMENT DISK WALL PART 2: DROPLET WEBER NUMBER AND ADHERED FUEL MASS
RÉSUMÉ
Behavior of adhesion diesel fuel spray impinging on a flat wall was investigated experimentally. Nonevaporated diesel spray was injected into a high-pressure vessel. A flat wall disk set vertically or inclined to the spray axis was prepared as an impingement surface. The mass of the disk with adhered fuel was measured using an electronic balance, and the fuel mass adhered to the disk surface was evaluated. It was found that the adhered mass was greatly affected by the Weber number which was obtained with impingement velocity and the Sauter mean diameter of the spray. To evaluate quantitatively the Weber number effect on adhered mass, a modified adhered mass ratio concerning the diameter of the impingement disk and its inclined angle was introduced. The modified adhered mass ratio rapidly decreased when the Weber number increased beyond 1000. Finally empirical relationships among the adhered mass ratio, the thickness of the adhered fuel film and the Weber number were derived.
