Introduction Efficient fluid transport is a cornerstone of numerous engineering systems, from petrochemical pipelines to micro‑fluidic biomedical platforms. Classical pipe designs, while mature, encounter a fundamental trade‑off: increasing flow rate typically incurs higher pressure losses, especially when operating near the laminar–turbulent transition (Re ≈ 2 000 for smooth circular pipes). Recent research has pursued passive flow‑control strategies —such as surface riblets, helical inserts, and porous liners—to delay transition and reduce drag without active actuation (see Table 1). Classical pipe designs
