Turbulent boundary layer modified by local polymer solution injection in low- and high-drag reduction states

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.
