Application of nanofluids in thermal technologies

Abstrakt

Nanofluids it is a relatively new category of thermal fluids that can serve as coolants, both in single- and two phase systems. However application of nanofluids in industrial applications requires faultless their thermophysical properties. Existing models originally developed for liquid/solid particles mixtures (slurries) fail in case of nanofluids. Moreover correlations used to calcuate heat transfer coefficients of conventional fluids can not be used in case of nanofluids as well. Therefore comprehensive investigations of thermophysical properties of nanofluids as well as studies concerning heat transfer of nanofluids are still indispensable. In this paper reults of the simultaneous measurements of essential thermophysical properties like dynamic viscosity and thermal conductivity of water based nanofluids are presented. The results of the experimental investigations of the single phase forced convection inside horizontal tubes and pool boiling characteristics are presented as well. Finally the experimental results of the performance of the prototype two-phase thermosyphon heat exchanger (TPTHEx) and selected type of brazed plate heat exchanger (PHEx) operated with nanofluids are reported.
