Thermal analysis of SUS 304 stainless steel using ethylene glycol/nanocellulose-based nanofluid coolant

Titania Nanofluids Based on Natural Ester: Cooling and Insulation Properties Assessment

“…As in other scientific fields, a possible improvement of the dielectric oils could arise from nanotechnology. The use of nanoparticles is growing in importance in medicine, in detection and treatments against cancer and in the administration of medicines [1,2]; in material science, for obtaining polymers and materials with enhanced properties for several applications [3][4][5]; in the treatment of industrial wastes, as they are able to capture polluting substances [6]; and in energy and thermal engineering, for energy and heat storage and cooling [7][8][9][10]. The research on dielectric nanofluids is being carried out under this context, aiming at the improvement of the cooling and the electrical isolation of the transformer wires.…”

Experimental Studies on Thermo-Physical Properties of Nanocellulose–Aqueous Ethylene Glycol Nanofluids

“…The samples were stirred for good mixing by using magnetic stirrer for half an hour. Finally, to produce highly stable and homogenous nanofluids, the mixed samples placed in ultrasonic processor for 1 h. named Fisherbrand model number-FB1505 which is similar equipment conducted by several researchers previously in experimental studies [30][31].…”

Nanofluid as an Alternative Coolant in Machining: A Review

“…Roy and Ghosh reported that the high temperature caused by the high velocities is reduced greatly by adding nanoparticles into cutting fluid due to the thermal properties of the nanoparticles [35]. According to Kadirgama et al, nanofluid is considered as higher heat transfer fluid due to their improved thermal conductivity [36]. Zhou et al, also share same opinion that the thermal conductivity enhancement helps to reduce the heat generated and also, act as a heat transfer medium and dissipate the heat generated at the cutting tool interphase [26].…”

“…Reduction in Surface roughness [32] Al2O3 nanoparticles 20-30% surface roughness reduction [33] Aluminum oxide (Al2O3) with vegetable oil 47.8% reduction [34] MWCNT with SAE oil Better surface reduction than conventional coolant [35] Multi wall carbon nanotube (MWCNT) with deionized water 30-35% reduction [36] Ethylene glycol (EG) with nanocellulose 0.251 -0.984 µm [40] Titanium dioxide (TiO2) with vegetable oil 34.7% reduction [37] Aluminum oxide/vegetable oil and graphite/vegetable oil Graphite/vegetable oil give much better surface roughness than aluminum oxide/vegetable oil [30] Al2O3 with carbon nanotube (CNT) in vegetable oil 8.72% reduction [26] Fe3O4 with conventional coolant 27.75% reduction [38] Copper coated Al2O3 with distilled water Surface roughness improved better than conventional coolant [39] Boric acid with vegetable oil 7.21% surface roughness enhancement [28] Nano boric Acid with coconut oil 24.74% enhancement than dry machining…”

“…Flank wear occurs after 292 seconds of machining [24] MWCNT nanofluid with distilled water Average flank wear occurs at cutting length of 960 mm [48] Al2O3 with vegetable oil Up to 26.5% of flank wear reduced [57] ZnO, CuO, Fe2O3 and Al2O3, with distilled water Crater wear and flank wear reduced [50] Ethylene glycol based TiO2 Flank wear occurs after 940 mm cut length Figure 1 shows the nanofluid forming a thermal barrier between chip and cutting tool. According to Kadirgama et al, the small chip shows the presence of less aluminum percentage proves that the nanofluid is capable to carry away the heat generated due to the superior thermal conductivity properties [36]. They also mentioned that carbon element presence in the nanofluid embedded the chip surfaces and act as a thermal barrier which reduce thermal expansion greatly.…”
