Abstract:Nanofluids, a suspension of nanomaterials in a basefluid, have shown promising improvements in their thermal properties compared to basefluids which are used for heat transfer nowadays. This interesting feature may offer unprecedented potential in cooling applications. Despite considerable theoretical and experimental research there still is no easy way to compare the nanofluid properties to its basefluid properties. This thesis summarizes the basics of nanofluids, for example how nanofluids are created and what their (dis)advantages are. Furthermore, an overview of currently used methods to compare nanofluids to their corresponding basefluids is given. Continuing this work, a figure-of-merit is derived based on entropy for a constant temperature and heat flux boundary condition. The figure-of-merit allows for an easy comparison of the thermal properties of nanofluids to their basefluids. Accordingly, the figure-of-merit is validated by comparing its value to literature values and their conclusions. Finally, measurements on thermal conductivity and viscosity will be performed to show that this figure-of-merit provides boundaries of other parameters for a nanofluid to be beneficial.
