Molten salt has been widely known to have much utilization, both as thermal storage and as a coolant in several energy generation systems. This study aimed to determine the thermophysical characteristics of molten salt in phase transition using computational fluid dynamics. ANSYS Fluent 2020 was used to solve the governing equations in the phase transition phenomena of molten salt. Experimental parameters from several references were used as input in computational modeling. The object in this study was molten alkali salt, both in pure NaNO3 and KNO3 or a eutectic mixture of both. The salt was put into a heater made of stainless-steel pipe with an outer diameter of 26.67 mm. Heat in the heater was modeled as a boundary condition on the walls of the pipe 10 cm long. The results showed that the molten salt phase transition occurred relatively fast around the melting temperature. © 2024 American Institute of Physics Inc.. All rights reserved.
