Abstract Under turbulent flow, wormlike micelles efficiently cause hydrodynamic drag reduction. However, it was demonstrated that beyond specific temperatures, the capacity of the micellar aggregates to produce drag reduction is abruptly lost. This can be associated with the decrease in size of long micellar chains, becoming shorter aggregates, in the sense that small aggregates are not capable to cause hydrodynamic drag reduction anymore. In this paper, we investigate the thermal effect on wormlike micelles under turbulent and quiescent regimes, in order to explore correlations between the size of the wormlike micelles and the hydrodynamic drag reduction phenomenon.

蠕虫状胶束在湍流和静止状态下的热行为

摘要 在湍流下，蠕虫状胶束有效地引起流体动力减阻。然而，已经证明超过特定温度时，胶束聚集体产生减阻的能力突然丧失。这可能与长胶束链的尺寸减小有关，变成更短的聚集体，从某种意义上说，小聚集体不再能够引起流体动力减阻。在本文中，我们研究了在湍流和静止状态下对蠕虫状胶束的热效应，以探讨蠕虫状胶束的大小与流体动力减阻现象之间的相关性。
