ABSTRACT

The paper presents a numerical simulation of conjugate, turbulent natural-convection air 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 model, and a high-Reynolds number k−ε turbulence model were used in this work. The finite-volume method has been used to solve numerically the three-dimensional conservation differential equations of mass, momentum, energy and turbulent kinetic energy, and its dissipation throughout the entire physical domain (solid and fluid). The effects of spacing between the heated electronic components and of the removal of heat input in one of the components were investigated.
