چکیده
In this study, a numerical analysis of different types of ceramic coating methods for a modified nanoparticle filtration system is investigated. The novelty of this study is based on proposing a nanofiltration model assisted by ceramic-based coating, leading to less energy consumption during the filtration process. The fluid velocity entering the nanofiltration system ranges from ۲۰ to ۷۵ m/s. Key parameters are identified and evaluated to assess the impact of energy losses on system performance. The results indicate that as the fluid velocity increases, both the pressure on the filter and the force on the system increase. The increase in shear stress on the wall also leads to an increase in the kinetic energy of the fluid, which can affect its turbulence. Three types of coatings, namely SiO۲, Sic, and Si۳N۴, were examined. The use of SiO۲ coating resulted in a ۲۱% decrease in temperature compared to the case without coating, thus reducing energy losses. The optimal coating thicknesses were found to be ۱ mm for SiO۲, ۱.۲ mm for SiC, and ۱.۴ mm for Si۳N۴. The results show that using SiO۲ coating can reduce energy losses by ۱۹.۳۴%. The pressure in the middle side of the filtration system is the highest due to the accumulation of nanoparticles, reaching a maximum value of ۱۶۰ kPa. Conversely, the pressure in the corners of the filtration system is the lowest, with a value of ۹۵.۱۳ kPa.کلیدواژه ها
