Nanofluids are just normal fluids with nanoparticles suspended in them. Nanofluids are a new kind of heat transfer coolant that have emerged as a result of recent advances in nanotechnology. The thermal characteristics of these fluids are bigger than those of traditional coolants. Since nanofluids provide fascinating new opportunities to improve heat transfer performance above pure liquids, they may be seen as the heat transfer fluids of the future. No such remarkable improvement is seen in particle-fluid suspensions with micrometer-sized particles. Conventional heat transfer fluids and fluids containing micro-sized metallic particles are anticipated to exhibit worse qualities when compared to nano fluids. The stability of the solution is enhanced and heat transmission capacities are substantially improved by using nanoparticles, which have a much greater relative surface area than regular particles.

With the use of 8mm, 10mm, and 12mm diameter HSS (M2) drills, spindle speeds of 1200, 1000, and 800 rpm, and feeds of 30, 40, and 50 mm/min, this study will perform tests to enhance the surface finish quality of GFRP (glass fibre reinforced polymer) composites work pieces. The Taguchi technique is a powerful tool for studying the impact of process parameters and finding the relationship between surface finish—the most important machinability factor— and cutting speed, feed, and depth of cut. The experimental results and the validated model equations are found to agree quite well.
