ABSTRACT A heat pipe with low thermal resistance and high conductance is one of the most effective transfer devices. It can move large amounts over a small cross-sectional area extremely little temperature variations between two limits. This study uses Design Expert software to evaluate performance various nanofluids as working fluid for pipe, including copper oxide, graphene iron titanium oxide. The base used in this analysis an aqueous solution n-Octanol. parameters considered are condenser flow rate, filling ratio, angle inclination, input. In order assess efficiency pipe's fluids, all operational factors assessed using Central Composite (CCD) matrix Response Surface Methodology during experiment design. experimental findings demonstrate that suggested model predict within 1% variation. As result, be forecast efficiency.
