The Ladtboy Tube: A Novel Low‑Loss, High‑Throughput Tubular Architecture for Laminar‑Dominated Fluid Transport Authors: [Your Name]¹, [Co‑author Name]², [Co‑author Name]³
Correspondence: [your.email@university.edu] A new tubular geometry, termed the Ladtboy Tube (LBT) , is presented for applications requiring sustained laminar flow at elevated Reynolds numbers while minimizing pressure drop and wall shear stress. The LBT combines a helical corrugated inner wall with a graded‑porosity outer sheath, enabling passive suppression of secondary vortices and enhanced momentum diffusion. Computational Fluid Dynamics (CFD) simulations (Re = 10⁴–10⁶) reveal up to a 45 % reduction in friction factor relative to conventional smooth circular pipes of equal hydraulic diameter, and a 30 % increase in volumetric throughput for a fixed pressure budget. Experimental validation in a 3‑m‑long prototype demonstrates repeatable performance across a range of Newtonian and non‑Newtonian fluids. Potential applications include high‑speed chemical reactors, biomedical micro‑circulatory devices, and aerospace fuel delivery systems. ladtboy tube
