The effects of suspending Copper nanoparticles into Argon base fluid inside a microchannel under boiling flow condition by using of molecular dynamic simulation

摘要

Present paper employs Molecular Dynamic Simulation (MDS) Method to study the effects of suspending 2, 4 and 6 Copper nanoparticles into Argon base fluid, flowing inside microchannel with square cross section under boiling flow condition. Fluid flow is supported by an external driving force of 0.002 eV/A at the inlet section of microchannel and boiling process is supported by boundary wall temperature of 108 K. Afterward, statistical approach is employed as new insight for data analysis of present MDS method. Finally, it is indicated that increasing number of suspended nanoparticles into Argon base fluid flow, expands density profiles of Argon base fluid as much as 20%, 35% and 55% in order of addition of 2, 4 and 6 Copper nanoparticles, while; they brings velocity enhancement as much as 17.8%, 32.6% and 52.8%. Also, temperature augmentation is reported as much as 30.7%, 50.45 and 69.5% respectively. It is analyzed that suspended nanoparticles empowers boiling condition and thermal driving force which is perpendicular direction with power of external driving force to move atoms. Therefore, it is concluded that due to disproportionation of statistical results, employing high fraction of suspended nanoparticles into base fluid is not always economical for practical application.
