Topology Optimization to Design a Hall-effect Thruster and Optimize its Energy Consumption

摘要

In this paper, density-based topology optimization is used to design Hall Effect Thrusters (HETs) electromagnetic circuits. This study aims to minimize the HET energy consumed under one constraint of generating a specific magnetic field inside its ceramic canal. Here, the design variables are the current densities inside the coils and the topology of the magnetic circuit. Thus, we propose an approach based on the SIMP (Solid Isotropic Material with Penalization) method and the adjoint method in order to solve the HET TO design problem. Consequently, an algorithm, named ATOP^TO, is developed and applied on an example of 2051 mixed-binary design variables.
