ARTICLE J. Cent. South Univ. (2019) 26: 2077-2087 DOI: https://doi.org/10.1007/s11771-019-4155-y Parametric study of natural convection over horizontal annular finned tube H. NEMATI1, M... difference and tube diameter on flow pathlines and local heat transfer were also studied. It was shown that pathlines remain mostly circular for different geometries. Moreover, the contributions of fin......
