Nanoparticles for phase change process of water utilizing FEM

Variations of needed time for full solidification with impose of fins and various sizes of nanoparticles is main goal of current article. Not only the needed time values but also, contours and solid front configurations were depicted in outputs which were obtained from (Finite element method) FEM modeling. Diameter of particles has various impact of thermal features and finding the best design needs considering various values of d(p). Time increases about 16.09% with augment of d(p) from 30 to 50 nm. So, it is not recommended to rise d(p) upper than 40 nm. Selecting d(p) = 40 nm instead of 30 nm results in 16.91% augmentation in solidification rate. To reduce the time of discharging to 614.8 s, the case with greatest length and d(p) = 40 nm should be selected. There was about 5.86% reduction in discharging time with augment of L. The minimum temperature of storage unit was obtained for d(p) = 40 nm and same behavior is examined for values of energy. (C) 2021 Elsevier B.V. All rights reserved.

Automated summary

This article focuses on studying the effects of adding fins and nanoparticles of different sizes on the time needed for solidification. The diameter of particles has a significant impact on the solidification rate, and it is not recommended to increase the diameter above 40 nm.
