Heat transfer treatment of system during freezing with implement of nanoparticles

Abstract

The present attempt investigates solidification through a tank equipped with T-shaped fins, a crucial aspect of cold storage technology. Utilizing the Finite Element Method (FEM) for simulation, implementation of a mesh adaptation technique enhances the accuracy of modeling. Equations are derived based on the assumption of neglecting velocity effects during solidification, simplifying the mathematical framework for analysis. Validation of the numerical approach is conducted through comparisons with previously published works, affirming the reliability of the methodology. A notable aspect of the study is the utilization of nanosized powders dispersed within the water, serving to bolster system performance. This innovative approach enhances water conductivity, thereby augmenting the rate of cold storage. Employing powders with a greater shape factor yields promising results, leading to a discernible decrease in completion time by approximately 10.6 %, attributed to heightened conductivity facilitated by the nanomaterial. Furthermore, the investigation explores the impact of varying volume fractions of particles on solidification time, revealing a significant reduction of approximately 32.78 % with the implementation of higher particle volumes.
