The working principle states that natural convection separately occurs within the three different layers, diffusion between the layers are minimal, allowing it to the mixture to reach high temperatures and the component to hold high amounts of heat.<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/aac211e9-7baf-4720-a8cd-a921010abadc\/0ab0c402-5173-4b61-b200-a92b0054bf45_schematic-of-a-salt-gradient-solar-pond-modified-from-kurt-et-al-2000.jpg?width=690&amp;upscale=false\" alt=\"\"><\/p>\n<p><\/p>\n<p>However, I still do not know the proper way to model a salt solution, considering the concentration of salt in the fluid.<\/p>\n<p><\/p>\n<p>I tried using multiphase VOF model for the three distinct fluids, having to define their density, Cp, viscosity, and thermal conductivity in the materials.
