Application of Nanofluids Seminar Report
In electronic industry, improvement of the thermal performance of cooling systems together with the reduction of their required surface area has always been a great technical challenge. Research carried out on this subject can be classified into three general approaches: finding the best geometry for cooling devices, decreasing the characteristic length and recently increasing the thermal performance of the coolant. The latest approach is based on the discovery of nanofluids.
Nanofluids are expected to have a better thermal performance than conventional heat transfer fluids due to the high thermal conductivity of suspended nanoparticles. In recent years there have been several investigations showing enhancement of thermal conductivity of nanofluids. The cooling performance of a water cooling kit with the addition of nanofluids is investigated. A real computer setup with a quad-core processor has been used to determine the effect of use of nanofluid on the cooling system in real practical condition.
Nanofluids are liquid-solid suspensions in which particles with the size of 1-100 nm are suspended in a heat transfer fluid. These fluids are engineered colloidal suspensions of nanoparticles in a base fluid. Nanofluids have been found to possess enhanced thermophysical properties such as thermal conductivity, thermal diffusivity, viscosity and convective heat transfer coefficients compared to those of base fluids like oil or water. The nanoparticles used in nanofluids are typically made of metals, oxides, carbides, or carbon nanotubes. Common base fluids include water, ethylene glycol and oil. Nanofluids have novel properties that make them potentially useful in many applications in heat transfer, including microelectronics, fuel cells, pharmaceutical processes, and hybrid-powered engines, engine cooling/vehicle thermal management, domestic refrigerator, heat exchanger, nuclear reactor coolant, in grinding, machining, and in boiler flue gas temperature reduction.
