This paper reports how heat transfer can be augmented by inserting a micelle squeezer at the inlet of the turbulent pipe flow drag-reduced by surfactant additives. The micelle squeezer gives very high shear to the flow and the rod-like micelles formed with surfactant molecules, which remarkably reduce both drag force of the flow and heat transfer, are broken by the high flow shear at the flow inlet. From this, the drag force is recovered in the very limited region below the micelle squeezer, but also heat transfer is recovered in the enough regions required for exchanging heat. This strategy can be applied for heat exchangers, which occupy the small part of district cooling flow system.
