Finite element analysis was conducted using Fusion 360 simulation software to evaluate the heated collector, test different heating channel configurations, and predict the resultant heating. The simulation, completed in a 3D environment, was performed by setting the temperature of the heater at the bottom of the borosilicate glass. Conductive heat transfer was considered between contacts below 0.1 mm, and heat radiation was accounted for throughout the system. To assess the accuracy of the simulations, the temperature of the flat collector was experimentally measured. It is important to note that the accuracy of this may be influenced by the composition of the commercially used components, the details of which may not be fully available. In fact, instances where the simulation underestimated the collector temperatures measured experimentally may be attributed to inaccuracy in the simulated thermal conductivity of the magnetic layer connecting the borosilicate glass with the flat collector.
