With the demand for energy continuous to grow globally, there is a need to make heat transfer equipment more energy efficient. At one hand, the exponential growth of electronics, communication and computer technology and their choice to go for miniaturization has put added pressure on the designer to create efficient thermal management devices for the systems. Particularly thermal conductivity of a fluid plays a vital role in development of energy efficient heat transfer equipment. An innovative idea is to suspend nano-sized solid particles in the fluid to improve heat transfer characteristics of the fluid. Nano fluids are the suspension of nano meter sized particles in base fluids as such as water. In convective heat transfer, number of other factors along with thermal conductivity effects heat transfer performance, so careful examination of convective heat transfer using nanofluid is required. The CFD simulation of heat transfer characteristics of a nanofluid in a converging pipe under constant heat flux was considered using Fluent software in the laminar flow.Al2O3 nanoparticles in water with concentrations of 5%, 10%, 15%, 20%, 25% and 30% are used in this simulation
