Application of asymptotic model for the prediction of fouling rate of calcium sulfate under subcooled flow boiling

In this work, a large number of experiments are performed to measure the heat transfer reduction and fouling resistance of CaSO4 aqueous solutions in a vertical upward annulus under subcooled flow boiling condition. Experiments are designed so that the effects of different parameters such as solution concentration (1.5 g/l to 2.2 g/l), wall temperatures (102–115 °C), heat flux (up to 400 kW/m2), and flow velocity (0.5–2 m/s) would be clarified....
