Abstract
All the region of circulatory system can not be analyzed using computational fluid dynamics (CFD), because the structure is so complicated and the analysis region is restricted by computer memory. In order to analyze the flows, it is necessary to simplifi and investigate the complicated network structure of vascular system quantitatively. We showed quantification of complicated structure using fractal dimension in our previous studies. This paper describes the relation between the flow field and the fractal dimension, and the computation scheme of volume flow distribution using box-counting method. One-dimensional model of cerebral vessel with considering tree structure was established.
