A system of Voxel CFD (Computational Fluid Dynamics) simulation technology cooperated with high energy X-ray CT (Computed Tomography) is developed. Computational model is obtained from "real object" using industrial X-ray CT, and then several CAE (Computer Aided Engineering) simulations are executed. These simulations are called "convergence technology simulations". They are expected to investigate the effect of difference between real product and 3D-CAD (Computer Aided Design) model, and improve the quality of products. Many of the past convergence technology simulations treated single material mechanical part because of the simplicity to obtain the model and to generate computational grid. In this study, a detailed 3D model of LCD (Liquid Crystal Display) projector, which is made of some materials such as glass, resin and metals, is obtained, by high energy X-ray CT, and flow simulation inside the whole body of the product is executed using Voxel CFD simulation to enable to generate computational grid, even if the geometry is highly complicated. The computational results are compared with the result of simulation from 3D-CAD model.
