By a News Reporter-Staff News Editor at Journal of Engineering -- Research findings on Materials Science and Engineering are discussed in a new report. According to news originating from Taipei, Taiwan, by VerticalNews correspondents, research stated, "This study aimed to investigate the effect of the cationic chitosan dispersant on the thermal conductivity, dispersion, and the suspension of 15nm Al2O3/water nanofluid. The study employed two-step method to mix the Al2O3 powder, deionized water, and dispersant to conduct an experiment of the settling properties and thermal conductivity of nanofluid in a stable environment, analyzing the adhesion of nanofluid to copper pipe walls in practical operations."
Our news journalists obtained a quote from the research from the National Taipei University of Technology, "The results indicated that 1.0wt.% Al2O3/water nanofluid with 0.05 wt.% cationic chitosan dispersant increased its thermal conductivity up to 4.1% and 12.6% compared with nanofluid with deionized water at the temperature of 15 degrees C and 55 degrees C. At the flow ratio of 2 L/min, the overall heat conductivity improved by 8.3% and 17.4%, respectively, under 60 W and 150 W heating power. The solution performed better in dispersion and suspension than that in the original sample with no cationic chitosan dispersant. The cationic chitosan dispersant, as a result, was proved to improve the dispersion and suspension of nanofluid."
According to the news editors, the research concluded: "It also helped to reduce the frequency of nanoparticles sticking to the pipe wall, increasing the practicability of nanofluid."
