Two-dimensional steady state laminaar convection in a region between two infiniteiy iong horizontal concentric square ducts is studied numerically.The basic differential equations for the conservation of mass,momentum and energy.using the Boussinesq approximation,arecomputed applying straightforward explicit finite difference scheme.The ratio of the inner (hot) and outer (cold) ducts is considered to be 1 to 5.Calculations have been made for Rayleigh number,Ra,up to 20000 and Prandtl number.Pr,in the range of 0.7 to 1000.Numerical values are presented for the flow field (stream function), temperature distributions,and both local and overall heat transfer rates.
