Fall 2023
It is well known that long-chain polymers and surfactants can significantly reduce the skin-friction drag of turbulent liquid flows; a phenomenon often referred to as rheological drag reduction. However, it is unclear if the mechanism for drag reduction is common among different types of polymers...

A reduction in skin-friction drag can lead to lower energy consumption in variety of transportation vehicles, and consequently results in a smaller environmental impact. Several methods have been presented to reduce the skin-fiction and one of these methods is to introduce an air layer at the...
