Direct numerical simulation of drag reduction in rotating pipe flow up
to $Re_{\tau} \approx 3000$
Direct numerical simulations (DNS) of rotating pipe flows up to $Re_{\tau} \approx 3000$ are carried out to investigate drag reduction effects associated with axial rotation, extending previous studies carried out at a modest Reynolds number (Orlandi & Fatica 1997; Orlandi & Ebstein 2000). The results show that the drag reduction, …
