A novel lower bound for the friction factor-Reynolds number product in laminar flows of Newtonian fluids through singly connected ducts
We revisit the analytical solution for steady, fully developed, pressure-driven flows of Newtonian fluids through n-sided cusped ducts and find that the friction factor–Reynolds number product is a non-monotonic function of n and converges to fRe=64/π2(≅6.486) in the limit as n→∞. To the best of our...
