Study of Diesel Spray Particle Velocity Field Using a Particle Image Velocimetry Setup

Aim To investigate the spray particle velocity and its distribution characteristics. Methods A set of PIV (particle image velocimetry) system was developed and used to observe and analyze the spray particle velocity field. Results and Conclusion Double-exposure image of the spray particle within the region of 10-50 mm from the nozzle tip was recorded and analyzed by the IBAS2000 analysis system. Some characteristics of the spray particle velocity and its dis-tribution were obtained.
