| Outline of Final Research Achievements |
We have developed computer composite software to analyze incompressible MHD(magnetohydro dynamics) carrying out fluid analysis and electromagnetic analysis alternatingly. We have adopted SUPG/PSPG(Streamline Upwind Petrov-Galerkin/ Pressure Stabilized Petrov-Galerkin) method as a stabilized finite element method for instability caused by advection and by incompressibility. In electromagnetic analysis, we have adopted A-method in which vector potential becomes unknown variables. As an application to the analysis of electromagnetic pumps, we carried out two dimensional analysis of duct flow under moving magnetic field. It is shown that iteration number required for solution of large scale linear equations can be reduced greatly by using algebraic multi-grid method. Furthermore, we have analyzed three dimensional lid-driven cavity flow under magnetic field.
