Abstract[English]
Disclosed is an apparatus for increasing the stability of nanofluids as well as increasing their evaporation enthalpy. Nanofluids, due to the improved thermo-physical potentials, have recently become a new generation of heat transfer fluids. Nanofluids with higher enthalpy of evaporation and stability are more desired in any application with nanofluid as the working fluid. The permanently stabilizing method is accomplished by a self-designed device. Most nanofluids in their common form may sediment after about 2 months while by applying the proposed method, the stability increases so that the nanofluid may not sediment even after 16 months. A dispersion stability is characterized by having less than 10% of agglomeration or sedimentation over the lapse of time, compared to an initial value in the case that the nanofluid is placed at room temperature in the predetermined space.[French]
Est divulgué un appareil d'augmentation de la stabilité de nanofluides ainsi que de leur enthalpie d'évaporation. En raison des potentiels thermophysiques améliorés, les nanofluides sont récemment devenus une nouvelle génération de fluides de transfert thermique. Des nanofluides à enthalpie d'évaporation et à stabilité supérieures sont préférés dans toute application où le fluide de travail est un nanofluide. Le procédé de stabilisation permanente est réalisé par un dispositif auto-conçu. Tandis que la plupart des nanofluides sous leur forme commune peuvent se sédimenter après environ 2 mois, par application du procédé proposé, la stabilité augmente au point que le nanofluide ne se sédimente pas même après 16 mois. Une stabilité de dispersion se caractérise par moins de 10 % d'agglomération ou de sédimentation pendant un laps de temps, par rapport à une valeur initiale au cas où le nanofluide est placé à température ambiante dans l'espace prédéterminé.
