Velocity distributions within a rotating type reactor were measured by a suspended tracer-particle method. In this paper, first of all, the outline of digital image processing technique of tracer particle motions within a rotating column was described, and then the applicability for this method was evaluated. Finally, some examples of measurement within a reactor were discussed.
Flow images visualized with suspended tracer particles were once recorded on the video tape recorder. The procedure was conducted as follows; 1) particle identification between different images, 2) selection of particle velocity vectors, 3) determination of particle velocity and 4) interpolation of velocity vectors to grid point over the flow field.
The results obtained were summarized as follows;
(1) Sample data were processed to check the validity of this method by using a circular disk dotted dummy-particle. From the point of view of flow visualization method, experimental criteria for this method were made clear.
(2) This method was applied to measure the velocity distribution within a rotating column type reactor. As the result, a reasonable velocity field was obtained.
