Numerical solutions of the Naviet‐Stokes equation have been used to extend Kuwabara's zero voiticity cell model to flow past banks of circular and elliptical cylinders for Reynolds numbers up to 50 and for porosities between 0.4 and 0.8. Total drag coefficients are presented. The complete energy equation was also solved numerically for Prandtl numbers of 0.7 and 7. Good agreement between existing experimental results for heat transfer in banks of circular cylinders and the numerical solution was obtained. In the assemblage, the ratio of the total heat transfer to pressure drop was highest when the main flow was parallel to the major axes of the elliptical cylinders. In all cases considered, the ratio of the minor to the major axis was 0.2.
