Inverse problems for a 2D heat conduction model connected with developing technologies of designing thermal concentrators are considered. The shells are assumed consisting of a finite number of sectors every of which is filled with homogeneous isotropic medium. By optimization method these problems are reduced to finite-dimensional extremum problems for the solution of which the particle swarm optimization is used. Rigorous optimization analysis shows that concentrators designed using optimization method have the highest efficiency in the class of devices under consideration and are easy for implementation.
