Abstract

AbstractThe implications of cooling fluids with suspended titanium dioxide nanoparticles in augmenting the heat transfer rate in the heat exchanger are discussed. The application of corrugated tubes for increasing the effectiveness of heat exchangers is studied in this work. In deionized water, the nanofluid is synthesized to get three different volume concentrations (0.25%, 0.5%, and 1%). The nanofluid's flow rate varies to 100 L/h, 150 L/h, and 200 L/h, respectively. An experiment is carried out in three corrugated tubes made of copper, with pitch values of 18, 20, and 25 mm, respectively. Optimization is carried out to determine the influence of nanofluid concentration, the mass flow rate of the nanofluids, and the corrugation pitch over the heat transfer rate. It is concluded that increasing the volume concentration of the nanoparticles in deionized water and the mass flow rate of the nanofluid enhances the heat transfer rate in the heat exchanger.
