| Research Abstract |
Calculation for fluid motion precisely in regions of very large aspect ratio such as river, tunnel or pipe without much computational costs is not easy. A new numerical method that is suitable for the calculation of incompressible flow in such region is developed. The idea of the method is that the original flow is expressed as sum of the "main flow" and the variation from the main flow. In this study, this new method is extended for the calculations of 3-dimensional flows with heat and thermal convection, and those of the flow with free surface.
