Abstract
The numerical simulation code with a finite difference method for unsteady three-dimensional thermal flows was developed in a Cartesian grid system. The code enabled us to predict flow fields around complicated geometries in a short pre-processing time. First, the present code predicted flow fields around a flat plate which was heated at a constant temperature, and it was confirmed that the results agreed with those obtained by analytical solutions in 20%. Finally the code was applied to the prediction of flow field of a LCD Projector which had highly complicated internal structures such as lamp, LCD panels, and electric parts etc.
