摘要

In this paper, we use a finite element discretization and a streamfunction-vorticity formulation to investigate natural convection in rectangular open cavities with the one vertical side heated and the two horizontal sides adiabatic. The numerical results concern streamfunction and temperature contours, and Nusselt number distributions for Pe=1, several values of the Rayleigh number and two different aspect rations. For the well documented square cavity problem, the average Nusselt numbers and the volumetric flow rates are compared with literature results.
