| Research Abstract |
In the human body, the scale of flow changes widely and it is difficult to consider macro and micro regions simultaneously. The purpose of this study is to construct a method of modeling and flow analysis for the multi-scale human respiratory and circulatory systems. We use the Cartesian grid to reduce computational costs. To handle the whole scale seamlessly, we apply the VOF method(the FAVOR method) for micro scale regions and use the Immersed Boundary method for the other regions to improve the accuracy of the shape representation. Some suitability and validity of the proposed method for the human respiratory systems are shown.
