Abstract: Now these days temperature effected on electronic devices and components, present investigation may be beneficial for the electronic industry in maintaining the electronic components under effective and safe operational conditions. For this purpose we constructed a mathematical model for analyzing convection heat and mass transfer of an incompressible viscous nanofluid through porous disks in the presence of metallic nanoparticles like Cu, Ti and Au for different problems. We compare the results of temperature profile by adding the convective boundaries. By use the governing equation from fluid dynamics we construct the Similarity transformations to convert the partial differential equations into non-linear ordinary differential equations. Numerical solutions of these non-linear ordinary differential equations are obtained by FD discretization (successive over relaxation). The influence of different parameters values of permeable Reynolds number as well as for relaxing/contracting parameter with fix value (percentage) of the nanoparticles volume fraction on the velocity and temperature profiles are shown graphically and table form. 1. INTRODUCTION The twenty first century is an era of technological development and has already seen many changes in almost every industry. The introduction of nano science and nanotechnology by the Nobel Prize winning physicist Richard Feynman in 1959. Feynman proposed the concept of micro machines. In 1974 Scientist Norio Taniguchi first used the term “Nanotechnology”. Began more than a century ago, the great scientist James Clark Maxwell [1] develop a theoretical model of the electrical conductivity of solid particles. Since then, the classical Maxwell model has been applied while investigation the thermal conductivity of mixtures of solid particles and liquids. However, all these studies have been conducted with millimeter or micrometer sized particles. The major problem with the use of micro particles is that they settle very rapidly in liquids. They also cause abrasion, clogging, and additional pressure drops. Furthermore, high particles concentrations are required to obtain appreciable improvements in the thermal conductivities of these suspensions. Nanofluids are new class of nanotechnology-based heat
