An experimental study on the heat transfer performance of a prototype molten-salt rod baffle heat exchanger for concentrated solar power

A prototype rod baffle shell-and-tube heat exchanger (RB-STHX) was proposed for concentrating solar power (CSP). For investigating the heat transfer of molten salt in the shell side, the RB-STHX was experimentally studied. A ternary salt Hitec and an oil were adopted as the heat transfer fluids in the shell and tube sides, respectively. Experimental data was firstly obtained when the salt temperature is 212.7–279.6 °C with the Prandtl number of...
