Many commercial solar thermal power plants rely on thermal storage systems in order to provide a stable and reliable power supply. The heat exchanger control strategies, to charge and discharge the thermal storage system, strongly affect the performance of the power plant. With the aim of developing advanced control strategies, a dynamic model of a shell-and-tube heat exchanger is being developed. This heat exchanger belongs to the CIEMATPSA molten salt testing facility. The goal of this facility is to study thermal storage systems in solar thermal power plants. During experimental campaigns performance losses with respect to design performance were noticed in the heat exchanger. Therefore and in order to develop an accurate heat exchanger model, thermal losses as well as heat transfer correlations on both fluid sides have been calibrated against experimental data.
