Numerical Simulation of Unsteady Turbulent Flow by Voxel Method

Abstract

A fluid analysis system that automatically and quickly generates meshes by the so-called voxel method was developed. This system was applied to calculate the flow characteristics in a magnetic disk drive, an LCD (Liquid Crystal Display) projector, a volute-type mixed-flow pump, and around an elevator. These calculations agreed well with the experimentally measured characteristics; thus it can be concluded that the developed voxel-method-based fluid analysis system can be successfully applied to numerical simulation of the fluid flow for designing turbomachinery and other fluid-engineering devices with complicated boundary forms.
