Research and Application of Complex Electromagnetic Field Numerical Simulation Algorithm Based on Moving Flow Field and Induced Electromagnetic Field

This research is dedicated to developing a numerical simulation algorithm to study the complex interaction of moving flow fields and induced electromagnetic fields. Through in-depth analysis of the theoretical basis of electromagnetic fields and combined with fluid dynamics equations, this paper constructs a comprehensive mathematical model. The model was numerically solved using the finite difference time domain (FDTD) method, which not only considered the stability and accuracy of the algorithm, but also optimized the calculation method. Through a series of application case analyses, including wireless energy transmission, electromagnetic compatibility analysis, environmental electromagnetic field assessment, and electromagnetic heating process, this paper verifies the effectiveness and practicability of the proposed algorithm. The research results show that this numerical simulation algorithm can accurately simulate physical phenomena under complex electromagnetic fields, which is of great significance to research and engineering practice in the field of electromagnetic applications. Although there are some research limitations, such as computational resource requirements and model simplifying assumptions, future work will be dedicated to further optimization of the algorithm, extension of the model, and exploring the possibilities of the algorithm in new application areas.
