Abstract
The flow characteristics of wall-impinging diesel spray near the wall were investigated in a constant volume vessel which can simulate diesel-engine condition. The wall-flow of a vaporized spray was visualized from the downstream point of view by using laser scattering from tracer particle, and velocity distributions were analyzed based on PIV. As the result, it is observed that the intermittent structure of fuel-air distribution appears near the wall occasionally. And, PIV result suggests that the vortex of which rotation axis is parallel with mainstream direction produces the intermittent structure.
