A Numerical Study on Faraday-Type Electromagnetic Flowmeter in Liquid Metal System, (Ⅰ) A Numerical Method Based on Magnetic Field and Electric Potential Field: FALCON Code

摘要

To predict the three-dimensional steady-state structure of electromagnetic phenomena in the Faraday-type Electromagnetic Flowmeter (EMF), a numerical simulation method using the Galerkin finite element method Has been adopted and formatted as a computer code, FALCON. As the induction equation for the induced magnetic field that is important in a liquid metal system, we have Presented B-φ formulation for the induced magnetic field and the electric potential field and A-φ formulation For the vector potential field and the electric potential field, and compared the computational efficiency of Both formulations.
