Cross-flow over tube bundle is generally encountered in practice in heat transfer equipments such asevaporators and condensers of power plants, air conditioners, refrigerators. In such equipment, one fluid moves throughthe tubes while the other moves over the tubes in a perpendicular direction. Steady state Navier-stokes and the energyequations are applied for cylinders having diameter of tube 0.02, 0.03 and 0.04m having constant p/d ratio for staggeredtube layout to obtain the numerical solutions of governing equations using Finite Element Method. .The effect of changeof diameter of tube on heat transfer and pressure drop has been analyzed using CFD tool. The contours of streamlines,pressure, velocity and temperature are generated to study the effect of change in diameter of tube. The purpose of thisstudy is to investigate the heat transfer and pressure characteristics at various tube diameters for staggered tube bundlelayouts in cross-flow. The result shows that as the diameter of tube increases the heat transfer increases with decrease intemperature and pressure drops.
