摘要

The paper presents a numerical simulation of conjugate, turbuletn naturla-convection ir cooling of three heated ceramic components having an aspect ratio equal to 1, mounted on a vertical adiabatic channel wall. A three-dimensional, conjugate heat transfer mdoel, and a high-Reynolds number k-ε turbulentce model were used in this work. The finite-volume method has been used to solve numerically the threed-imensional conservation differential equations of mass, momentum, eneryg and turbuelnt kinetic energy, and tis dissipation throughout the entire physical domain (soild and fluid). The effects of spacing between the heated electronic components and of the remvoal of heat input in one of the components wee investigated.
