شناسایی نانوفیلد ها به عنوان یک وسیله انتقال حرارت پیشرفته برای سیستم های انرژی

Nanofluids are exciting new materials came into existence due to innovative idea put forth and research performed by Choi. In fact nanofluids are colloidal suspension of nanoparticles in base fluids. Lot of research has been done and going on since its inception in early 1990s.Advanced heat transporting medium is requirement of modern technologies and efficient devices. In order to increase efficiency of heat absorbing and transporting devices, efficient working fluid can drastically change the economic and manufacturing scenario. In absorption of solar energy, performance of nanofluids as reported by researcher is very promising. Since performance of nanofluids as heat transporting medium depends on various parameters such as thermal conductivity, density, viscosity, convectional heat transfer coefficient In characterization of nanofluids for experimental work authors have experimentally analyzed that how thermophysical parameters of SiO2 /water nanofluid vary with respect to base fluid with temperature and volume concentration and particle size.
