  • G071054 Simultaneous measurement of Flow Velocity of Fuel Spray Droplets and Ambient Gas by Dual Camera LIF-PIV Technique

抄録

Velocity distributions of the spray droplets and ambient gas in a non-evaporating Diesel spray were measured by the LIF (Laser Induced Fluorescence) - PIV technique which adopts two CCD cameras. Simultaneous measurement of the both velocity distributions inside the spray could be made in the particular region 4-5mm inside from the spray tip. The axial velocity of the spray droplets is much larger than that of the ambient gas at 4-5mm inside from the spray tip. The axial velocity of the spray droplets becomes the similar value as the ambient gas in the region l-2mm inside from the spray tip. In this region, the spray droplets velocity vector changes its direction to the radial (outward) direction, whereas the ambient gas velocity vector keeps the axial direction (downward).
