Knowledge of the rheological behaviour of nanofluids is found to be critical in deciding their suitability for convective heat transfer applications. Nanofluids also have special acoustical properties and in ultrasonic fields display additional shear-wave reconversion of an incident compressional wave; the effect becomes more pronounced as concentration increases.
In analysis such as computational fluid dynamics (CFD), nanofluids can be assumed to be single phase fluids; however, almost all new academic papers use a two-phase assumption. Classical theory of single phase fluids can be applied, where physical properties of nanofluid are taken as a function of properties of both constituents and their concentrations. An alternative approach simulates nanofluids using a two-component model.
Optimizing of cooling processes is very important in many industries, such as power generation, transportation, automation, and electronics. The equipment for heat transferring to achieve higher efficiency requires minifying of equipment and increase the heat transfer rate per unit area. Heat transfer plays an important role in many industrial processes. Optimization of energy consumption is also very important. There are active methods to improve heat transfer. The application of electric field and nano-fluid are part of active methods, respectively. The nano-fluid is obtained from the dispersion of nano particles in original fluid, which is usually low thermal conductivity. These particles are very effective in increasing the heat transfer surface, creating turbulence and increasing thermal conductivity.
