Abstract: Micro channels are of current interest for use in compact heat exchangers, micro reactors where very high heat transfer performance is desired. These electronic equipments are virtually synonyms with modern life applications such as appliances, instruments and computers. The dissipation of heat is necessary for the proper functioning of these instruments Micro channels provide very high heat transfer coefficients because of their small hydraulic diameters. Here, an investigation of fluid flow and heat transfer in micro channels is conducted. The computational fluid dynamics (CFD) model equations will be solved to predict the hydrodynamic and thermal behaviour of Micro channel. This study will be aimed at investigation of the forced convection heat transfer and flow characteristics of waterbased Al2O3nanofluids inside a horizontal circular tube in the laminar flow regime under the constant wall temperature boundary condition. The analysis will be carried out for concentrations 0.05% , and the diameter of nano particle is 40 nm. The simulation will carried out for inlet velocities range from 1.3 -6.5 m/s. analysis will be validated with experimental results provided in the literature as a part of validation. To carry out this study twodimesnional circular duct of will be taken as micro channel. The geometry of the problem and meshing of it will be made in ANSYS ICEM CFD. The models have to be solved by ANSYS Fluent 14.0 solver. The results will be shown that the use of the Al2O3nano particles leads to an enhancement in the heat transfer.
