Numerical study on air-side flow and heat transfer characteristics of steel tube brazing snake-like fins for direct air-cooled condenser

The air-side flow and heat transfer characteristics of steel tube brazing snake-like fins for direct air-cooled condenser is numerical simulated with the help of computational fluid dynamics (CFD) software. The affect between the comprehensive heat transfer performance indicators and the fin height and wind speeds is discussed. The correlation of flow resistance and heat transfer coefficient with the wind velocity were also obtained by fitting simulation results and the verification of numerical results were presented by the comparisons of the numerical results with the designing datas.
