Topology Optimization of Magnetothermal Systems Considering Eddy Current as Joule Heat

This research presents a topology optimization for manipulating the main heat flow in coupled magnetothermal systems. The heat generated by eddy currents is considered in the design domain assuming an adiabatic boundary. For a practical optimization, the convection condition is considered in the topological process of the thermal field. Topology design sensitivity is derived employing the discrete system equations combined with the adjoint variable method. As numerical examples, a simple iron and a C-core design heated-up by eddy currents demonstrate the strength of the proposed approach to solve the coupled problem
