Pressure Drop of Nanofluid through a Shell and Tube Heat Exchanger

An experimental investigation was carried out to measure pressure drop of γ-Al2O3/water and TiO2/water nanofluids through a shell and tube heat exchanger. Nanofluid flows inside tubes while hot distilled water runs through shell. The measurements were done for a wide range of nanoparticle concentration and Reynolds number. Results emphasize on the lowering of pressure drop for nanofluids and more reduction happens at higher concentration.
