A numerical study for solid and serrated annular finned tube bundles

Annular finned tube bundles are commonly used for heat recovery systems. Nowadays, systems important in the energy economy. Cross-flow exchangers, one of exchanger types suitable waste fins utilized cross-flow exchangers a long time. In this study, two annular fin geometry, namely solid and serrated fins, were studied numerically exchangers. All numerical analyses performed ANSYA-FLUENT program geometries designed 3-D geometry. Numerical results obtained different geometry validated separately with literature. It is seen that analysis found to be compatible analyses, five Reynolds Numbers six geometric parameters studied. Effects these investigated determine flow thermal performance. According results, performance about 8.2% higher than while decreases by 7.5%.
