| In this paper, the combining methods of numerical simulation and experimental study were used. Respectively with water, 50% glycerol and 85% glycerol as the heat transfer working fluid, the local flow resistance and heat transfer performance of smooth tube and converging-diverging tube with 2 different twisted-tapes inserted were studied in numerical simulation method. At the same time, both temperature field and velocity field of different pipes fluid mediums were compared and analyzed. The results show that at the condition of high turbulence (15000 |
