Nonlinear thermal analysis of functionally graded convective-radiative porous fin by adomian decomposition method

The increasing miniaturization of modern electronics has motivated mechanical and electronic designers to conduct research on thermal management of high-performance microprocessor-based systems. High computational performance of electronic systems usually requires increased power and on-chip power density requirements, both of which involve increased heat dissipation. However, in order to provide effective cooling of electronic systems, fins are used as a passive approach to reduce thermally induced failures in electronic components. In this study, nonlinear thermal analysis of functionally graded convective-radiative porous longitudinal fins using Adomian decomposition method is discussed. The variation of material properties, which are generally neglected in functionally graded materials, with temperature will be discussed in this study. The effects of the axial variation of the heat transfer coefficient as well as its dependence on temperature on the temperature distribution will be discussed.
