Abstract
In the present paper numerical analysis of heat transfer and laminar flow structures are studied for staggered tube bundle in crossflow. This study consists of two parts. At the first part isoterms and streamlines are shown for both only single tube heated and all tubes heated cases. At the second part effect of Reynolds number is examined. The stream functionvorticity formulation is used to solve the laminar, steady state Navier-Stokes equations and energy equation by applying Gauss-Seidel over-relaxation technique. Transverse and longitudinal tube spacing is fixed as 1.75x1.5 and results are found for Re=325 and 650.
