摘要：The heat transfer performance of the pulsating flow in the convergent-divergent tube is analyzed. The influence of pulsation amplitude, pulsation frequency and divergent segment-convergent segment ratio on heat transfer and resistance of the tube was simulated by numerical simulation. The results show that the heat transfer performance of the pulsating flow in the convergent-divergent tube is better than the fluid steady flow in the tube. The heat transfer is enhanced by about 11.4% compared with the fluid flow in the tube was steady. The pulsating flow in the tube strengthens the heat transfer, but also increases the resistance. Through the analysis of enhanced heat transfer comprehensive index, the heat transfer performance of the tube under pulsating flow conditions is significantly enhanced.
