Preparation of Bauxite/Deionized Water Nanofluid and Experimental Investigation of Its Thermophysical Properties

In this study, bauxite/deionized water nanofluid was prepared by two-step method and its thermopyhsical properties were experimentally investigated. Bauxite milled high-energy spex-type ball milling attritor. nanoparticles with a size of 38 nm (2% weight) Sodium Dodecyl Benzene Sulfonate (0.5% doped into the deionized while preparing bauxite nanofluid. Ultrasonication applied for three hours to obtain stable colloidal dispersions nanoparticles. It has been seen that thermal characteristics better than water. The lower surface tension smaller contact angle base fluid. However, conductivity specific heat increased 8.47% 4.4% compared water, respectively.
