A Nanofluid is a mixture of a liquid (basic fluid) with particles measuring 1-100 nm (nanoparticles). 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 with basic fluid (aquades) which is then carried out by the stirring process using a magnetic stirrer. Furthermore, vibrat…
