The most common method for making nanofluids is a two-step procedure. The nanoparticles, nanofibers, nanotubes, and other nanomaterials used in this method are first chemically or physically transformed into dry powders. Intense magnetic force agitation, ultrasonic agitation, high-shear mixing, homogenizing, and ball milling will be used to spread the Nano powder in a base fluid. The two-step procedure is the most cost-effective way to manufacture nanofluids on a large scale because Nano powder synthesis techniques have already been scaled up to commercial production levels. Nanoparticles agglomerate due to their enormous surface area and surface properties. Surfactants are often utilized to increase nanoparticle stability in fluids. Surfactant performance at high temperatures, especially in high-temperature applications, is critical.
