In the present research, the innovative measurement systems for the dispersed two-phase flow fields was developed. The laser light scattering by the sphere was analyzed. Bubble dissolution process, which diameter is below several micrometer, was firstly investigated. The system was also applied to the measurement of the behavior of evaporating liquid hydrocarbon with high temporal resolution beyond several kHz. Moreover the meso- and nano-scale particle image velocimetry technique in vacuum was newly developed by means of the scanning electron microscope in conjunction with an ionic liquid.
