Abstract
The problem of laminar forced convection in a two-dimensional channel with arrays of thermal sources is studied numerically. The surfaces of the thermal sources are assumed to be isothermal. In order to promote the accuracy of the result, numerical computation is performed with alternating direction implicit (A.D.I.) method and SIMPLER algorithm. The primary purpose of this paper is to study the fundamental heat transfer phenomena in “L.S.I.” packages, which are widely used in microelectric equipments recently. The contribution of this study is not only on academic purpose but also on industrial application. Influence of Reynolds number on Nusselt number of thermal sources is discussed. Calculations are made under the conditions of different arrangements of the thermal sources. Flow patterns, pressure and temperature distributions are demonstrated.
