| Research Abstract |
We have experimentally studied daily nonlinear phenomena over the whole period of this research in order to simulate those phenomena on computer and to clarify the mechanism. In particular, we have found that the initial pattern formation of coffee fractals on milk is explained by viscous fingering. Since we have tried to analyze those phenomena 'as is', it is required to develop multiscale approach. In the field of the multiscale analysis, we showed efficiency of the multiscale method for time-direction, which leads to the next study on the multiscale analysis of nonlinear phenomena.
