AB - Particles less than 100 nanometers in size are suspended in a base fluid such as water, oil, and ethylene glycol. These nanoparticles are floating in the nanofluid. The purpose of this study is to research the operation of a counter-flowing, double-pipe heat exchanger using two distinct nanofluids as cooling media. Titanium carbide and carbon nanotubes combine to form alkaline water, a basic fluid. The purpose of this research was to assess the performance of a counterflow double-pipe heat exchanger using water with different concentrations of titanium carbide and carbon nanotubes. Alkaline water had a particle volume concentration of 0.06, and its nanofluid-flow rate was 0.03. Using a heat exchanger, water is heated to 65°C while nanofluids are heated to 35°C, both at a constant input velocity. The speed of both fluids is constant. The findings demonstrate that nanofluid outperforms water in heat absorption across a broad range of flow speeds. Heat exchangers benefit from the improved thermal characteristics of nanoscale fluids.
