Abstract

In this paper, natural convection heat transfer from two horizontal heated cylin- ders in a rectangular cavity is analysed, both by computational and experimental method. The two horizontal cylinders are located one above the other in the vertical symmetry plane of the cavity. A finite-element procedure based on the streamfunction-vorticity formulation of the momentum and energy equations is employed for the numerical solution of the flow and thermal field. Computed results include plots of the flow and ther- mal field patterns, and plots of the distribution of the local Nusselt number on the cylinder surfaces. The experimental apparatus consists of a test cell, made by a rectangular enclo- sure filled with air, and of a hologra
