Abstract

Nanofluid is a suspended colloid of nanoparticles with dimensions smaller than 100nm then mixed with a base fluid. Preparation of nanofluids is prepared according to the parameters set in Orthogonal Array L9(34). The preparation process begins with mixing Hybrid Al2O3-TiO2 nanoparticles and aquades base fluid which is then stirred with a magnetic stirrer. Then vibration is carried out with an ultrasonic system as an agglomerator. Then an evaluation of the stability of the nanofluid was carried out by the sedimentation and centrifugation methods. Next, density examination with a pycnometer and viscosity using a falling ball viscometer. Then the density and viscosity data were processed using ANOVA statistical calculations to obtain optimal conditions for the nanofluid. A3, B3, C1, and D1 are the optimal level settings of nanofluid density. A2, B3, C3, and D3 are the optimal level settings of the nanofluid viscosity. The results of scanning electron microscope (SEM) observations showed the shape of small cubic and spherical particles and particle sizes ranging from 5 nanometer to 210 nanometer. Keywords: Hybrid Al2O3-TiO2, Nanofluid , ANOVA.
