41 Fluid MapperによるPoisson電界の可視化・解析

The authors have been studied visualization and analysis methods of electrostatic fields. In this paper an electric field with space charges is simulated by a fluid mapper with a fixed sand-bed which behaves as distributed sources or sinks of fluid flow. The fluid mapper method visualizes the lines of electric force in axisymmetric three dimensional fields satisfied with Poisson's equation. Moreover, the equi-potential surfaces in the electric fields are represented graphically by a flow pattern from this method. Finally the experimental results of this method show that the justification of numerical results calculated by the computers can be inspected by the flow patterns.
