Key Points

Turbulent boundary layers showed increased drag reduction when modified by local polymer solution injection.
The fluid dynamics metrics indicated a drag reduction of up to 30% under specific conditions.
Assessment using fluid dynamics simulations highlighted variations between low- and high-drag reduction scenarios.
Findings suggest potential designs for more efficient fluid transport systems; further experimental validation is needed.
