Abstract

Aiming at improving heat transfer efficiency of heat exchanger tube, this paper proposes two types of tape fitted in tubes with adaptive transform capabilities(different twisted ratio and shrink ratio at different temperature) and study on the heat transfer and flow characteristics inside the tube. In this study, the performance of inserts is simulated by commercial computational fluid dynamics (CFD) solver. Two types of inserts are presented as twisted tape and ripple tape. To value the performance of the tapes, the results simulated by CFD are presented in dimensionless form such as Nusselt number(Nu), friction factor(f) and performance evaluation criteria (PEC). Meanwhile, through the results, several dimensionless correlations are developed to predict the heat transfer characteristics and flow resistance of the heat exchanger tube with different types of tape.
