| Outline of Final Research Achievements |
To evaluate the performance of Venturi scrubber which is one of the filter vents necessary for resuming nuclear power plant operations, development of measuring technology of micro droplets moving with high speed in the scrubber is required. In this study, we established the measurement method of fine particles by optical interference fringe method using laser light. Moreover, we investigated the possibility of application to droplets.
In the experiments, fine particles with several hundred nm to several μm in diameter were individually measured by the method. The result shows that the number of particles can be measured by the method. In addition, we found the relationship between the obtained electrical signals and the particle diameters. The result means that particle size measurement is possible. In the droplet experiment, the electrical signals were obtained as same as the particle experiment. Therefore, we confirmed that the droplet measurement is possible by this method.
