| 内容記述 | A brain blood structure is extracted from MRI (Magnetic Resonance Imaging) voxel data of a head, and modeled for CFD (Computational Fluid Dynamics) analysis. In order to treat complex structure of the blood vessel with branches, we introduce two major techniques in the blood flow simulation; a high-accurate numerical scheme IDO (Interpolated Differential Operator) which has been developed to solve Navier-Strokes equation as a compact scheme by using local Hermite interpolation, and AMR (Adaptive Mesh Refinement) method to gather fine meshes around the blood flow in Cartesian grid to describe the geometry of the vessel accurately keeping less computation. The computational results show the spatial profile and the temporal change of the velocity and the pressure. It is possible to find the high pressure area in the brain, and the branch ratio of the blood flow for several cases. | |||||
