Abstract

Abstract

With the development of bionics, bionic technology has better drag reduction and heat transfer effects. Inspired by the fish-scale bionic concept, three biomimetic enhanced heat transfer tubes are proposed. The effects of different depths, spacings and angles of bionic enhanced heat transfer tubes on the fluid flow and heat transfer characteristics in the turbulent flow regime (Re=15700−62900) are studied by numerical simulation. The results show that the three bionic enhanced heat transfer tubes all have perfect heat transfer enhancement effect. The greater the depth, the smaller the spacing and the smaller the angle, the better heat transfer enhancement effect. Under the same conditions, the comprehensive performance and entropy generation of bionic enhanced heat transfer tubes are analyzed, and it is found that the second type has the best comprehensive performance, the largest performance evaluation criteria (PEC) and the smallest power loss.
