Abstract:

The flow and heat transfer characteristic in outward convex corrugated tube combined with insert twisted tube (CT) was numerically studied based on the three-dimension RNG k-ε model. A comparison is proposed between the numerical results and experimental results in order to check the reliability of numerical model. Comparative study on flow and heat transfer between the CT and conventional smooth tube (ST) is performed in order to review the compound heat transfer enhancement mechanism. The results show that compared with ST, the heat transfer performance and overall heat transfer performance of CT increase by 1.48 and 1.3 respectively, and more obvious in the low Reynolds number. Detached vortex is formed between the corrugatoion and twisted tape in CT, breaking the thermal boundary layer. Disturbance is increased by twisted tape in the main flow region, meanwhile, turbulence kinetic energy increase. Therefore, compound heat transfer enhancement is achieved by synergistic effect between the corrugation and twisted tape.

Key words: outward convex corrugated tube combined with twisted insert, RNG k-ε, compound heat transfer enhancement, overall heat transfer performance
