Summary
In recent years, researchers have shown a great interest in studying the viscosity of nanofluids,\nparticularly nanofluids having various types of metal oxide nanoparticles dispersed in base fluids and they\nhave found anomalous results on this crucial property of nanofluids. This chapter critically reviews the\nliterature and recent research progress in the viscosity of metal oxide based nanofluids. Experimental\ninvestigations on the viscosity of nanofluids containing titania and silica nanoparticles in silicone oil\nconducted by the authors are also reported. Like thermal conductivity, viscosity data of nanofluids vary\nconsiderably among the various studies. Nanoparticles concentration and fluid temperature play an\nimportant role in changing the viscosity of nanofluids and the effects of these factors on this property of\nnanofluids are demonstrated. Studies show that nanofluids exhibit both Newtonian and non-Newtonian\nshear-thinning flow natures and their rheological behavior depends on various factors such as nanoparticle\nconcentration, shear rate and temperature. The review revealed that all these nanofluids have significantly\nhigher viscosity when compared to their base fluids and increasing the concentration of nanoparticles\nincreases the viscosity of nanofluids. Although viscosities of both the base fluids and the nanofluids\ndecrease mostly nonlinearly with increasing temperature, temperature has little influence on the increase\nor decrease of the relative viscosity of nanofluids. Despite numerous efforts devoted to develop a model\nfor the viscosity of nanofluids, success has not yet been achieved and thus none of the existing models\ncan accurately predict the viscosity of nanofluids and explain the underlying mechanisms of heat transfer.\nMost of the reported models in the literature are mainly obtained from the regression of researchers` own\nviscosity data.
