Abstract

In the present study, the turbulent CONVECTIVE HEAT TRANSFER and PRESSURE DROP characteristic of alumina (Al2O3) nanoparticle dispersions in water is studied experimentally in a horizontal tube. The boundary condition imposed on the tube wall is that of uniform heat flux. Ten temperature sensors are also used to measure the surface temperature. One differential pressure transmitter (DPT) is employed to measure the differential pressure between inlet and outlet of the tube. A flow loop facility is constructed to conduct the experiments. To do this, Al2O3 nanoparticles of 40 nm size are characterized and dispersed in distilled water to form stable suspension containing 1.0%, 1.5% and 2.0% by volume concentrations of NANOFLUIDS. Results indicate that heat transfer coefficients increase with nanofluid volume concentration. The enhancement of the Nusselt number is about 22% at Re=13500 using 2% alumina nanoparticles compared to distilled water. The experimental data are also compared to predictions made by using the traditional single-phase CONVECTIVE HEAT TRANSFER PRESSURE DROP in turbulent regime. The measured pressure loss when using NANOFLUIDS is almost equal to that of the base fluid.
