A Computational Study of Particle Mass Transport during Melting of NePCM in a Square Cavity with a Single Adiabatic Side

Nanostructured phase change materials (NePCM) are that contain different types and sizes of colloidal I removed the word particles. Many investigations in literature assess those type to investigate their thermal performance. However, there is a discrepancy between experimental observations numerical results melting process NePCM because most models do not count for mass transfer In current work, we will consists copper nanoparticles suspended water geometry square cavity, heated from two sides, cooled one side, remaining side thermally insulated. Our model account particles using one-fluid mixture enthalpy porosity accounting process. We found adding lead deceleration process, as described by experiments, reduction convection intensity. suspension containing 10% mass, be about 2.2% compared pure water. Most convected away flow cells toward bottom especially near isolated right cavity. findings indicate incorporating transport leads significantly improved prediction behavior NePCM.
