“…CNTs are fullerene-related structures that consist of either a grapheme cylinder or a number of concentric cylinders [9]. Choi et al [10] measured the effective thermal conductivity of SWCNTs dispersed in synthetic (poly-α-olefin) oil and reported the enhancement up to a 150% in conductivity at approximately 1 vol.% CNT, which is by far the highest thermal conductivity enhancement ever achieved in a liquid [11]. Guu [12] proposed that the surface morphology, surface roughness and micro crack of AISI D2 tool steel machined by the electrical discharge machining (EDM) process were analysed by means of the atomic force microscopy (AFM) technique.…”

Nanofluids for grinding process are prepared by mixing the multiwall carbon nanotubes with SAE20W40 oil. In this experimental study, the surface roughness and micro cracks are analysed. The material AISI D3 tool steel is most frequently use for mould and dies which is preferred to analyse the surface characteristics. Experimental results indicate that the surface finish of the machined work piece increases from micro level to nano level. L8 orthogonal array was used to optimize the machining parameters in Taguchi design of experiment technique using Minitab 15 software. Empirical model for the prediction of output parameters has been developed using regression analysis and the results are compared empirically for with and without nanofluids in grinding process. The analysis of variance and F test were used to determine the significant parameter affecting the surface roughness. Atomic force microscopy analysis indicated that carbon nanotube mixed with nanofluid in grinding process has improved the surface characteristics like surface roughness and micro cracks.

“…Nanofluids are nanotechnology-based heat transfer fluids by dispersing nanometer-sized solid particles in a conventional heat transfer fluids at low particle concentrations. Choi and his team [1][2][3] showed that nanofluids have the potential of being recognized as a new generation of coolants for vehicle thermal management due to their higher thermal conductivities than the base fluids. Leong et al [4] applied nanofluids in engine cooling and found that overall heat transfer coefficient increased with the usage of nanofluids in engine cooling compared to ethylene glycol (i.e.…”

This study focused on the evaluation of TiO2 nanofluid coolant for automobile engine cooling applications. It was observed that, about 3% of thermal conductivity enhancement and above 10% convective heat transfer enhancement could be achieved with the usage of 1.0 wt.% TiO2 nanofluid coolant compared to base coolant without nanoparticles. More importantly, corrosion-inhibiting properties of TiO2 nanofluid coolant were investigated, which indicated that the nanofluid coolant possess the characteristics of a qualified engine coolant should have. The evaluation results showed that the nanofluid coolant could be a promising engine coolant for automobiles.

Choi et al (2001) measured the effective thermal conductivity of MWCNTs dispersed in synthetic (poly-α-olefin) oil and reported the enhancement up to a 150% in conductivity at approximately 1 vol% CNT, which is by far the highest thermal conductivity enhancement ever achieved in a liquid (Lockwood and Zhang, 2005). Solid lubricants are useful for conditions when conventional liquid lubricants are inadequate such as high temperature and extreme contact pressures.…”

This work investigates the machining characteristics of American Iron and Steel Institute (AISI) D2 tool steel with copper as a tool electrode during electrical discharge machining (EDM) process. The multi wall carbon nano tube (MWCNT) is mixed with dielectric fluids in EDM process to analyze the surface characteristics of surface roughness. Regression model were developed to predict the surface roughness (SR) in EDM process. In the development of predictive models, machining parameters of pulse current, pulse duration and pulse voltage were considered as model variables. The collection of experimental data adopted Box-Behnken central composite design (CCD). Analysis of variance (ANOVA) and F-test were used to check the validity of regression model and to determine the significant parameter affecting the surface roughness. Later, the AISI D2 tool steel was analyzed and the parameters are optimized using MINITAB software, and regression equation are compared with and without MWCNT used in EDM process. The average 34% of surface finish was improved by using carbon nano tube (CNT) mixed as dielectric fluid. The maximum test errors for regression model using copper electrode are 8.18% for without CNTs and 5.44% for with CNTs. The R 2 value of developed empirical model for SR with MWCNTs is 69.45% compared without CNT is 55.4%. The high R 2 value indicates that the better the model fits the data.
