Numerical results of axial velocity variations, temperature variations, friction factors and Nusselt numbers are presented. Effects of the secondary flow created by free convection and the viscosity varied by temperature are observed to increase heat transfer. Further the effect of inserts in circular tubes is also found to increase heat transfer. Chou Fu-Chu 周復初 1996 學位論文 ; thesis 79 zh-TW
