Laminar combined free and forced convection in flow through a finite rod array is investigated using a finite difference scheme. The geometrical dimensions simulate those of a CANDU-type pressurized water reactor. The rods are deemed to dissipate heat uniformly, whereas the shell wall is maintained adiabatic. Temperature of the inner rod surface at a non-nodal and nonorthogonal intersection is estimated using a six-point interpolation scheme. Velocity and temperature profiles together with transport rates are presented indicating variations due to buoyancy, power skew, eccentricity, and number of rods in the array.
