This paper reports on a numerical study of simultaneously developing flow in the entrance region of a cascade of thin parallel horizontal plates with a uniform flow at upstream infinity. Results obtained by ADI solution of finite difference equations for the Navier-Stokes and energy partial differential equations are extrapolated to zero mesh size with extended Richardson extrapolation. Nusselt numbers, incremental heat transfer number, and thermal entrance length are presented for Reynolds numbers between 40 and 2000; Pr = 0.2, 0.7, 2, 7, 10 and 100; and constant wall temperature and heat flux boundary conditions.
