Evaluation de l'intérêt énergétique des nanofluides dans l'usage des machines frigorifiques

Abstract : The aim of this study is to evaluate the potential interest of nanofluids in the cooling systems including in the European project FRISBEE. This nanoparticles increase the thermal conductivity of the base fluid where they are in suspension, so we have faster thermal exchanges in order to decrease the pumping power. This study allowed to resume in the literature the using of nanofluids for lows temperatures (between 10°C and minus 35°C) and the conclusion is we have fews experimentations in this domain. To second, a numerical study allows to evaluate the nanofluid's performance versus base fluid's performance which are used in factory, and find an optimum of concentation and type of nanoparticles to use in laminar and turbulent. With this values, we can evaluate the energy savings for a company. To finish, an experimental study was made on the aggregation for see how much time the nanofluid was stable.
