2132 2 色レーザ PIA の開発と水噴霧測定  [in Japanese] Development of Two-Color Laser PIA and Its Application to Water Spray Measurement  [in Japanese]

Full-cone water spray is measured to test the performance of the two-color laser particle image analyzer (PIA) developed by the authors. Water spray is issued from a single-hole nozzle with an orifice diameter of 0.5mm at an injection pressure of 0.5MPa. Both droplet diameter and two-component velocities are measured at several radial locations, all 80mm downstream of the nozzle, The data measured are compared with those obtained for the same water spray by using the previously established technique based on stereo imaging. Reasonable agreement between them is obtained.
