REVIEW OF CONVECTION HEAT TRANSFER AND FLUID FLOW BY NANOFLUID

Abstract

Heat transfer enhancement techniques refers to different method used to increase the heat transfer rate, In that Heat Exchanger using different nano fluid. Nano fluid are used in broad range of engineering application due to their increase thermo-physical properties like that Viscosity, thermal conductivity, thermal diffusivity, and convective heat transfer coefficient. The properties change of Nano fluid is depend on the volumetric friction of nanoparticles, shape, and size of the nanoparticle. Nanofluid result from the mixture of base fluid with nanoparticle having dimension of (1-150) nm, with very high thermal conductivities. In this we taking different volume concentration such as (0.1%, 0.2%, 0.5%, 1%, 5%) . the other properties of nano fluid such as its specific heat, density, can be calculated. A review on the experimental works on the specific application of nanofluid is presented.
