摘要：
The energy demand is more in the world due to increase in the populations. The sustainable and clean renewable energy is required to meet the demand. The solar energy with nanofluid used as heat transfer medium is the best alternative source to enhance the rate of heat transfer. The nanofluids are the suspended nano sized particles in the water, ethylene glycol or oil. The stability analysis of Al2O3 ethylene glycol carried out using zeta potential method. The 20nm sized Al2O3 nanoparticles with volume concentration from 0.01% to 1% in ethylene glycol is used as nanofluid to study the effects of concentration on convective heat transfer coefficient (HTC) and wall function HTC at temperature 298K and mass flow rate 0.033kg/s. The investigation also carried out to study the effects of concentration on its thermophysical properties of nanofluid. ANSYS fluent software used to carry out the numerical analysis with suitable thermal boundary conditions. © 2023. Carbon Magics Ltd.
